Regional airlines connect hundreds of smaller U.S. communities with major aviation hubs, giving residents access to jobs, business markets, tourism, education, healthcare, and the wider national transportation system. Their role is especially important where driving to a large airport can take hours and local demand is too small to support frequent mainline service.
Quick Answer
Regional airlines connect small and rural communities to larger hub airports. According to the Regional Airline Association, they served 94.3% of U.S. airports receiving passenger service in 2025, while about two-thirds of commercially served airports depended on regional airlines as their only source of scheduled air service.
A regional route might connect a smaller community in Montana with a hub such as Denver, allowing travelers to reach employment, universities, specialized medical care, family, and onward flights without making a long highway trip first. Regional service can also support tourism and business development by making a community easier to reach.
The scale of that network is substantial. In 2025, the Regional Airline Association reported that regional airlines served 635 U.S. airports, accounted for 32.3% of scheduled U.S. passenger departures, and provided the only air service available at about two-thirds of commercially served airports.[1]
That does not mean every community receives frequent service or that every regional route is economically secure. Smaller markets remain sensitive to operating costs, airline fleet decisions, staffing, local demand, and the availability of government support. When a community has only one or two useful departures a day, losing even a single route can have an outsized effect on residents and businesses.
Key Takeaways
- Regional airlines served 94.3% of U.S. airports receiving passenger service in 2025, and about two-thirds of commercially served airports relied on them as their only source of air service.[1]
- Regional air service can support local employment, tourism, business activity, education, healthcare access, and connections to larger transportation networks.
- Smaller communities face pressure from higher operating costs, limited local demand, fleet changes, staffing needs, and fewer alternative flights when disruptions occur.
- The Essential Air Service program helps eligible communities retain a link to the national air transportation system when scheduled service would otherwise be difficult to sustain.[2]
- Many large regional airlines operate under FAA Part 121, but smaller commuter and public-charter operations can use different regulatory structures, so “regional airline” is not one universal FAA certificate category.
- Aircraft noise and emissions remain environmental concerns, while newer aircraft, operating practices, and international standards continue to push aviation toward quieter and more efficient operations.[5]
How Regional Airlines Work in the U.S.
A regional airline is generally an airline that uses smaller aircraft to connect smaller cities with larger airports or to operate shorter routes within a larger carrier’s network. The term describes the airline’s role in the market more than one single regulatory category.
Many familiar regional flights operate through capacity purchase agreements. Under this model, a regional carrier supplies the aircraft, crews, maintenance, and day-to-day flight operation while a larger airline markets the flight under a brand such as American Eagle, Delta Connection, or United Express. The major airline typically controls important commercial functions such as scheduling, ticket sales, and network connections.
This is why the airline name printed prominently on a ticket or boarding pass may not be the company actually operating the aircraft. Travelers can usually find the operating carrier next to wording such as “operated by” in their reservation.
Republic Airways provides a current example. After completing its merger with Mesa Air Group on November 25, 2025, the combined company announced a fleet of 310 Embraer E-Jets and continued flying for major-airline partners under capacity purchase agreements.[6]
Note: “Regional airline” does not automatically mean “Part 121 airline.” Many of the largest U.S. regional carriers operate under Part 121, the same regulatory part used by major scheduled airlines, while some smaller commuter operations and public-charter services use other FAA or DOT operating structures.
The Economic Impact of Regional Airlines on Local Communities
Direct Employment Opportunities
Regional air service supports employment both at airlines and at the airports they serve. Jobs can include pilots, flight attendants, mechanics, customer-service agents, airport staff, ground handlers, security personnel, rental-car employees, and other support roles. Some workers are employed directly by an airline, while others work for airports, contractors, or businesses that depend on passenger traffic.
Multiplier Effect on Local Businesses
An airport with reliable passenger service can make a community more attractive to hotels, restaurants, rental-car companies, conference organizers, employers, and visitors. The effect varies by market, but better transportation access can make it easier for businesses to meet customers, recruit workers, receive visitors, and reach larger markets.
Air service can also influence where companies choose to locate or expand. A business that needs regular access to customers or corporate offices in larger cities may place considerable value on reaching a major hub with one short local flight instead of several hours of driving.
Improved Logistics and Connectivity
Regional airports can also support time-sensitive business logistics and cargo movement, although cargo capacity on scheduled passenger flights varies by airline, aircraft, and route. Agricultural producers, manufacturers, healthcare organizations, and other businesses may benefit from having an airport connected to a larger transportation network even when most scheduled regional flights are primarily passenger services.
The broader economic value therefore comes from more than the passengers sitting on one aircraft. Easier access can affect business travel, tourism spending, workforce mobility, supplier relationships, and investment decisions throughout the surrounding area.
The Challenges Faced by Regional Airlines in Serving Remote Areas
Despite their importance, regional airlines face difficult economics in thin markets. Aircraft, crews, maintenance, insurance, airport services, fuel, training, and regulatory compliance all carry substantial costs. A route with too few passengers or too little revenue may be difficult to sustain even when the community considers the service essential.
Federal support can help in qualifying markets. The Essential Air Service (EAS) program[2] was created after airline deregulation to help eligible communities retain a minimum connection to the national air transportation system. Subsidies are awarded for qualifying community service when necessary; that is different from saying regional airlines as a whole depend on EAS to survive.
Smaller airports can also have fewer gates, maintenance resources, replacement aircraft, crews, or alternative departures available than major hubs. That makes disruption recovery harder. Weather can delay or cancel any aircraft, but at an airport with only a few flights per day, one cancellation can leave travelers with far fewer same-day alternatives.
Airlines have also shifted portions of their fleets toward larger regional aircraft. Carrying more passengers on each departure can improve economics, but a larger aircraft may be difficult to fill several times a day in a small market. The result can be fewer frequencies even when the total number of available seats does not fall as sharply.
Note: Pilot availability remains important, but the picture has changed since the immediate post-pandemic shortage. Staffing has improved at many regional carriers, while long-term retirements remain a concern. The Regional Airline Association reported in 2025 that nearly half of the Part 121-qualified pilot workforce would reach the federally mandated retirement age of 65 within fifteen years.[1]
The Importance of Regional Airlines in Supporting Tourism and Business Development
| Metric | Current Context |
|---|---|
| Number of Regional Airlines | There is no single official count because “regional airline” describes a business role rather than one unique FAA certificate class. The U.S. DOT maintains a current list of certificated air carriers.[4] |
| Passenger Traffic | Large regional carriers transport tens of millions of passengers each year. SkyWest, for example, remains one of the largest U.S. regional carriers by passenger volume. |
| Scheduled Departures | Regional airlines operated 32.3% of U.S. scheduled passenger departures in the RAA’s 2025 report.[1] |
| Airport Connectivity | 94.3% of U.S. airports receiving passenger service were served by regional airlines in 2025.[1] |
| Only Source of Air Service | About two-thirds of commercially served U.S. airports relied on regional airlines as their only source of air service in the RAA’s 2025 report.[1] |
| EAS Communities | The number and status of subsidized communities can change as contracts and eligibility change, so travelers and communities should use the U.S. DOT’s current EAS reports rather than relying on a permanent fixed count. |
| Job Creation | Employment varies widely by carrier and community, but regional service can support airline, airport, hospitality, rental-car, maintenance, tourism, and other local jobs. |
Regional airlines can be especially valuable to tourism markets that are far from large airports. A short connecting flight to an airport near a national park, ski area, coastal destination, or historic town can make a trip practical for travelers who might otherwise choose a more accessible destination.
Visitor spending can then reach hotels, restaurants, guides, attractions, rental-car companies, retailers, and local artisans. The size of that impact depends on how many travelers actually use the service and whether the schedule provides useful connections.
Regional airlines also facilitate business travel by connecting companies in smaller markets with customers, investors, suppliers, and larger offices. Industries such as technology, agriculture, manufacturing, energy, and professional services may have operations spread across multiple regions, making reliable transportation links valuable even when a community does not generate enough traffic for large mainline aircraft.
A technology company in a smaller city, for example, may be able to reach investors or partners through one regional flight to a hub rather than sending employees on a long drive before the main portion of the trip even begins.
Pro Tip: Compare regional flying with driving using total door-to-door time, not flight time alone. Include the drive to each airport, parking, security, connection time, ground transportation at the destination, and the effect of having fewer backup flights if your original departure is canceled.
What Regional Air Service Means for Travelers
The biggest advantage of regional service is usually access. A nearby airport can eliminate hours of driving to a major hub and put a traveler directly into a larger airline network.
The tradeoff is frequency. Small airports may have only a few departures per day, so travelers have fewer recovery options after a cancellation or missed connection. A larger airport may offer many later flights to the same destination, while a regional airport may require waiting until the next day.
Passengers should also check the operating carrier when booking. A ticket sold by a major airline may be flown by a regional partner using a regional jet or turboprop. Checked-baggage, loyalty, ticketing, and rebooking arrangements are generally coordinated through the marketing airline when the flight is sold as part of that carrier’s network, but aircraft-specific carry-on limits can differ because smaller cabins and overhead bins have less space.
For travelers choosing between driving and flying, the best option therefore depends on schedule, fare, total travel time, connection reliability, parking, ground transportation, and how important it is to have multiple backup departures.
The Environmental Impact of Regional Airlines on Local Communities
Regional aviation creates environmental tradeoffs. Aircraft produce greenhouse-gas emissions, and airport operations can expose nearby communities to aircraft noise. Noise can be particularly sensitive when flight paths pass close to residential areas.
The International Civil Aviation Organization identifies aircraft noise as a major source of community reaction around airports. Its Balanced Approach to Aircraft Noise Management combines quieter aircraft technology, land-use planning, noise-abatement operating procedures, and operating restrictions where appropriate.[5]
Smaller aircraft are not automatically more or less environmentally efficient than larger aircraft on every trip. Per-passenger emissions depend on aircraft design, distance, passenger load, route, fuel burn, and how many seats are occupied. Comparing a regional flight with driving is also context dependent because vehicle occupancy, highway distance, airport access trips, and other factors change the result.
For that reason, the strongest argument for regional air service is often connectivity and travel-time access rather than a universal claim that flying produces fewer emissions than driving.
Newer aircraft, more efficient engines, sustainable aviation initiatives, improved operating procedures, and emerging electric or hybrid-electric aircraft could reduce some environmental impacts over time. However, emerging aircraft still face certification, infrastructure, range, and economic hurdles before they can replace conventional regional fleets at scale.
As communities place greater emphasis on sustainability, regional airlines and airports will face pressure to improve efficiency while preserving the transportation access residents and businesses depend on.
The Future of Regional Airlines in an Evolving Aviation Industry
Consolidation and Competition
Consolidation remains an important trend in regional aviation because carriers depend heavily on scale, fleet economics, pilot staffing, and contracts with larger airline partners. Republic Airways and Mesa Air Group completed their previously announced merger on November 25, 2025. The combined Republic Airways Holdings announced a fleet of 310 Embraer E-Jets and more than 1,300 daily departures.[6]
Consolidation can create larger, more efficient operators, but it can also reduce the number of independent regional carriers available to bid for contracts or serve thin markets. Communities ultimately care less about the corporate structure than whether reliable and affordable service remains available.
Digital Transformation
Most passengers now encounter a regional flight through the booking system of a larger airline rather than by shopping directly for a regional carrier. That makes seamless reservations, mobile boarding passes, disruption alerts, baggage information, and rebooking increasingly important.
Regional operators also use digital systems behind the scenes for crew scheduling, maintenance planning, dispatch, operational monitoring, and communication with their airline partners. Better systems can improve reliability, but technology cannot fully compensate for limited aircraft, crews, or frequencies in a small market.
Sustainable Operations
More efficient regional jets, improved turboprops, operational changes, sustainable aviation fuels, and eventually electric or hybrid aircraft may reshape regional aviation. Shorter routes are frequently discussed as possible early markets for new propulsion technology because the required range is lower than on long-haul flights.
Even so, a new aircraft must be certified, economically viable, supported by trained crews and maintenance systems, and matched with suitable airport infrastructure before it can become a practical replacement for today’s fleet. The transition is therefore likely to be gradual rather than immediate.
The Role of Government Support in Sustaining Regional Airlines
Government support is particularly important where a community’s traffic is too small to make scheduled commercial service financially attractive on its own.
The U.S. Essential Air Service program[2] was established after airline deregulation to preserve a minimum level of scheduled air access for eligible communities. DOT generally does this by subsidizing service when necessary and awarding contracts to carriers through a competitive process.
EAS should not be confused with every form of small-community aviation assistance. Other programs can help communities develop or attract air service, while airport infrastructure programs can fund eligible airport improvements. The programs have different eligibility rules, purposes, and funding structures.
EAS requirements also change over time. Communities may need to meet passenger-use, distance, and subsidy-per-passenger rules, subject to statutory exceptions or waivers. For that reason, travelers and local officials should use DOT’s current community lists and status reports rather than assuming that an airport’s EAS status is permanent.
Government investment in runways, navigation systems, terminals, safety equipment, and other airport infrastructure can also help smaller airports remain capable of supporting commercial operations. Those improvements do not guarantee airline service, but they can remove operational barriers and make airports better positioned to retain or attract carriers.
The Benefits of Regional Airlines in Providing Access to Healthcare and Essential Services
Regional air service can be especially valuable when specialized healthcare is concentrated in larger cities. A resident of a remote community may be able to fly to a hub and reach a major medical center much faster than by driving the entire distance.
The same connectivity can help students reach colleges or vocational programs, allow specialists and other professionals to travel into smaller communities, and give residents easier access to government, business, and family services located elsewhere.
During a disaster or public-health emergency, a functioning commercial airport and scheduled air network can also contribute to community resilience by moving people and some supplies. However, scheduled regional passenger airlines should not be confused with dedicated air ambulances, military flights, disaster-response aircraft, or specialized medical-evacuation operators.
Note: For a medical emergency, use the appropriate emergency medical system rather than relying on a scheduled commercial flight. The healthcare value of regional airlines is mainly their ability to improve routine and planned access to larger medical centers.
About two-thirds of commercially served U.S. airports rely on regional airlines as their only source of air service, according to the Regional Airline Association’s 2025 report.
Are Regional Airlines as Safe as Major Airlines?
Aircraft size by itself does not determine the safety standard that applies to a flight. The important question is which operator is flying the aircraft and under which regulatory authority it operates.
The FAA states that Part 121 covers regularly scheduled air carriers including major U.S. airlines and regional air carriers.[3] A regional carrier operating under Part 121 must comply with the Part 121 rules applicable to its operation, including FAA oversight, training, maintenance, operational, and certification requirements.
However, not every service commonly described as regional or small-community air transportation operates under Part 121. Smaller commuter services and some public-charter operations can use different regulatory structures. DOT’s EAS program, for example, notes that eligible communities may be served by certificated air carriers, commuter carriers, public-charter services, and, in Alaska, air taxis.[2]
So a smaller regional jet or turboprop should not be assumed to be less safe simply because it has fewer seats, but it is more accurate to evaluate the operating carrier and regulatory framework than to say every regional service follows exactly the same rules.
Regional airports can also affect the practical side of trip planning. Families traveling through smaller terminals may find a double travel stroller useful when moving children and luggage through airports. Travelers who need data service away from their normal carrier can compare a portable WiFi hotspot, while those preparing for a trip can also browse these travel gift ideas.

Frequently Asked Questions
What is a regional airline?
A regional airline generally operates shorter routes with smaller aircraft, often connecting smaller communities with major hub airports. In the United States, the term describes the carrier’s network role rather than one single FAA certificate category.
How is a regional airline different from a major airline?
Regional airlines usually operate smaller aircraft and shorter routes, while major airlines operate broader networks and larger aircraft. Many regional carriers fly under capacity purchase agreements for major-airline brands and feed passengers into those airlines’ hubs.
Why does my ticket show one airline while another operates the flight?
Many major airlines contract regional carriers to operate flights under brands such as American Eagle, Delta Connection, and United Express. The major airline markets the itinerary, while the regional partner may provide the aircraft and crew. Your booking normally identifies the operating carrier with “operated by” wording.
What types of aircraft do regional airlines typically operate?
Regional airlines commonly use regional jets such as Embraer E-Jets and Bombardier CRJ-family aircraft, while some markets use turboprops. Aircraft choice depends on route demand, range, airport requirements, fleet economics, and the airline’s agreements with larger partners.
What are the advantages of using a regional airline?
The main advantage is access. A regional flight can eliminate a long drive to a large airport and connect a smaller community directly with a major airline hub. The tradeoff is that small airports usually have fewer departures and fewer backup options after disruptions.
Do regional airlines have partnerships with major airlines?
Yes. Many regional airlines operate under capacity purchase or codeshare arrangements with major airlines. These flights can appear under brands such as American Eagle, Delta Connection, or United Express while being operated by a separate regional carrier.
What is the Essential Air Service program?
Essential Air Service is a U.S. Department of Transportation program that helps eligible communities retain a minimum connection to the national air transportation system when scheduled service would otherwise be difficult to sustain. DOT can subsidize qualifying service and periodically selects carriers to operate it.
Why do some small communities lose regional flights?
Routes can be reduced when passenger demand is too low relative to operating costs, airlines move to larger aircraft, crews or aircraft are needed elsewhere, a partner changes its network, or financial support ends. Smaller airports can therefore have fewer flights even when residents still value the service.
Are regional airlines subject to the same safety regulations as major airlines?
Many large U.S. regional airlines operate under FAA Part 121, the same regulatory part used by major scheduled airlines, and must comply with the Part 121 requirements that apply to their operations. However, some smaller commuter and public-charter services operate under different regulatory structures, so the exact rules depend on the operating carrier rather than aircraft size alone.
