Chattanooga Airport (CHA), officially Chattanooga Metropolitan Airport, gives travelers a compact alternative to driving to a larger regional airport. Its scheduled passenger service includes major hub connections and several nonstop leisure routes, but the available destinations and operating days can change throughout the year.
Quick Answer
Chattanooga Airport is currently served by four passenger airlines: Allegiant Air, American Airlines, Delta Air Lines, and United Airlines. They offer nonstop flights to major hubs and leisure destinations. CHA does not currently list scheduled nonstop international service, so international trips normally require a connection.
Key Takeaways
- The four airlines currently marketed at CHA are Allegiant Air, American Airlines, Delta Air Lines, and United Airlines.
- American, Delta, and United connect Chattanooga with major airline hubs across the United States.
- Allegiant Air provides limited-frequency leisure service, primarily to Florida destinations.
- Some routes are seasonal or operate only on selected days, so the airport’s destination list does not guarantee daily or year-round service.
- Southwest Airlines and Frontier Airlines do not currently appear on Chattanooga Airport’s official airline list.
Airlines That Currently Fly From Chattanooga
The official Chattanooga Airport airline and destination page currently identifies four scheduled passenger airlines. Each serves a different mix of hub and leisure routes.
| Airline | Type of service | Main use |
|---|---|---|
| Allegiant Air | Low-cost, limited-frequency leisure routes | Nonstop trips to selected Florida markets |
| American Airlines | Hub and seasonal nonstop service | Domestic and international connections through airports such as Charlotte and Dallas–Fort Worth |
| Delta Air Lines | Hub-focused scheduled service | Connections through Atlanta, Detroit, and New York |
| United Airlines | Hub-focused scheduled service | Connections through Chicago, Denver, Houston, and Newark |
Note: An airline may sell a flight that is operated by one of its regional partners. The operating carrier will appear during booking and on the confirmation, but the ticket is still marketed through American, Delta, or United.
American Airlines
American Airlines connects Chattanooga with several important business and connecting markets. Its currently listed destinations include Charlotte, Chicago O’Hare, Dallas–Fort Worth, Washington, D.C., and seasonal Miami service.
Charlotte and Dallas–Fort Worth are especially useful for onward connections. Miami can also provide access to destinations in the Caribbean and Latin America when the seasonal Chattanooga flight is operating.
Delta Air Lines
Delta Air Lines currently lists nonstop service from Chattanooga to Atlanta, Detroit, and New York LaGuardia. Atlanta is Delta’s largest connecting hub and can provide one-stop access to a wide range of domestic and international destinations.
New York and Detroit schedules may vary by season or travel date. Travelers should confirm that a nonstop appears for their exact dates rather than assuming every listed market operates every day.
United Airlines
United Airlines currently connects Chattanooga with Chicago O’Hare, Denver, Houston, and Newark. These airports can open one-stop itineraries to destinations across the United States and abroad.
Chicago is listed as a shared Chattanooga market for United and American. Comparing both airlines can help travelers find a better departure time, connection, or fare.
Low-Cost Airline Service at Chattanooga
Allegiant Air is the low-cost carrier currently listed at Chattanooga Airport. It focuses on nonstop leisure routes rather than high-frequency hub connections.
Current Allegiant markets listed by the airport include Fort Lauderdale, Orlando, Punta Gorda, and the Tampa Bay area. Allegiant’s schedules often operate only on selected days, and some routes may pause outside their main travel season.
The lowest advertised fare may not include every service a traveler needs. Before booking, compare the final cost after adding baggage, seat selection, priority boarding, and any other optional charges.
Pro Tip: When comparing Allegiant with a connecting itinerary on another airline, compare the total trip cost and total travel time. A nonstop can still be the better value even when its base fare is not the lowest.
Current Nonstop Destinations From Chattanooga
Chattanooga Airport currently lists the following nonstop destination markets. Airport codes are included because some airline destination names refer to secondary airports rather than the area’s largest airport.
| Destination | Airport | Airline | Planning note |
|---|---|---|---|
| Atlanta | ATL | Delta | Major domestic and international connecting hub |
| Charlotte | CLT | American | Major American Airlines connecting hub |
| Chicago | ORD | American and United | Compare both airlines for schedule and connection options |
| Dallas–Fort Worth | DFW | American | Useful for western U.S. and international connections |
| Denver | DEN | United | Useful for western destinations |
| Detroit | DTW | Delta | Verify operating dates and frequency |
| Fort Lauderdale | FLL | Allegiant | Limited-frequency leisure service |
| Houston | IAH | United | United hub with domestic and international connections |
| Miami | MIA | American | Seasonal service; confirm travel dates |
| New York | LGA | Delta | LaGuardia service may vary by schedule |
| Newark | EWR | United | New York-area and United connecting service |
| Orlando area | SFB | Allegiant | Uses Orlando Sanford, not Orlando International Airport |
| Punta Gorda | PGD | Allegiant | Convenient for parts of Southwest Florida |
| Tampa Bay area | PIE | Allegiant | Uses St. Pete–Clearwater International Airport |
| Washington, D.C. | Washington-area service | American | Confirm the arrival airport on the booking screen |
Note: A destination appearing on the airport’s route list does not guarantee daily or year-round service. Airlines can change routes, flight times, aircraft, and operating days, so verify the schedule directly with the airline before making nonrefundable plans.
Regional Flights and Operating Partners
Travelers may see a regional airline’s name on the aircraft, boarding pass, or flight details even though the ticket was purchased from American, Delta, or United. This happens because major airlines contract regional partners to operate some shorter routes under brands such as American Eagle, Delta Connection, or United Express.
The operating partner can change by flight number, season, or schedule. For that reason, it is more useful to choose among the four airlines marketed at CHA than to treat every regional operator as a separate airline option.
Neither Nashville nor Birmingham currently appears on Chattanooga Airport’s main scheduled nonstop destination list. Travelers headed to those cities should compare driving with any available connecting itinerary rather than expecting a scheduled nonstop regional flight.
International Travel From Chattanooga
Chattanooga Airport does not currently list a scheduled nonstop international destination. Travelers can still begin an international itinerary at CHA by connecting through a major hub.
Common connecting possibilities include:
- Atlanta: Delta connections to Europe, Latin America, the Caribbean, Asia, and other regions.
- Charlotte, Dallas–Fort Worth, or Miami: American Airlines connections to domestic and international destinations.
- Chicago, Denver, Houston, or Newark: United Airlines connections throughout the United States and abroad.
When comparing international itineraries, look beyond the first connection. Consider total travel time, connection length, airport changes, baggage rules, and whether all flights are issued on one ticket.
Warning: Do not book separate tickets with a short connection unless you understand the risk. If the first flight is delayed, the second airline may not be required to rebook you, and checked baggage may need to be collected and checked again.
Popular Routes and Flight Frequency
Hub routes such as Atlanta, Charlotte, Chicago, and Dallas–Fort Worth are often the most useful for travelers because they provide access to onward connections. Leisure routes operated by Allegiant generally have fewer weekly departures and may not operate every day.
For many Chattanooga travelers, the best flight is the itinerary with the lowest total travel time and least risky connection, not simply the one with the lowest advertised fare.
A route’s frequency can change between the published booking seasons. Instead of relying on a fixed weekly number, search the exact dates you intend to travel and check nearby dates when your schedule is flexible.
How to Find Better Airline Deals From Chattanooga
Compare the complete trip price
Include baggage fees, seat fees, parking, fuel, meals, and ground transportation in your comparison. A lower fare from Nashville or Atlanta may cost more overall after adding the drive, parking, and an overnight hotel.
Search flexible dates
Moving a departure or return by one or two days can reveal a different fare or a nonstop option. This is especially useful for limited-frequency leisure routes.
Check both nonstop and connecting itineraries
A nonstop usually reduces disruption risk, but a connecting itinerary may provide a better departure time or significantly lower total price. Compare the scheduled duration and connection length before choosing.
Confirm which airport you are using
“Orlando” service from Chattanooga currently refers to Orlando Sanford International Airport, while the Tampa-area route uses St. Pete–Clearwater International Airport. Check the airport code before arranging a rental car, hotel, cruise transfer, or theme-park transportation.
Compare nearby airports carefully
Southwest Airlines does not currently fly from Chattanooga. Travelers willing to drive to another airport can use Southwest’s Low Fare Calendar, but the comparison should include drive time, parking, baggage costs, and the possibility of returning late at night.
Planning Your Travel Day at Chattanooga Airport
Chattanooga Airport currently advises passengers to arrive about two hours before departure. Its website also states that baggage larger than a carry-on must be accepted at the airline ticket counter no later than 45 minutes before scheduled departure.
The 45-minute baggage deadline should not be treated as a recommended airport arrival time. Travelers still need time to park, walk to the terminal, check in, clear security, and reach the gate before boarding closes.
- Check in online when the airline allows it.
- Confirm the flight status before leaving home.
- Allow extra time during weekday morning peak periods, holidays, and severe weather.
- Verify baggage size and weight rules directly with the airline.
- Use the airport’s official parking page for current lot availability, construction notices, and rates.
Note: Contact the airline, not the airport, for rebooking, checked-baggage tracking, flight credits, refunds, and airline-provided accessibility assistance. The airport does not have access to individual airline reservation or baggage systems.
What to Do After a Cancellation or Major Schedule Change
If an airline cancels a flight or makes a significant schedule change and you decide not to accept the alternative itinerary, you may be entitled to a refund under applicable U.S. Department of Transportation rules.
Review the airline’s message carefully before accepting a travel credit. The DOT’s airline refund guidance explains when a cash refund may be available and how refunds should be issued.
Airport Growth and Future Airline Options
Chattanooga Airport has already completed its largest passenger-terminal expansion in more than three decades. The project added approximately 26,000 square feet, new passenger gates, greater checkpoint capacity, additional concessions, restrooms, and renovated concourse space.
The additional capacity gives the airport more room to support existing service and discuss future routes with airlines. Chattanooga Airport also reported a record 556,958 passenger boardings in 2024, exceeding its previous pre-pandemic record.
Future routes will still depend on airline strategy, local passenger demand, aircraft availability, and route performance. Until an airline or the airport announces a route and opens it for sale, travelers should treat proposed destinations as possibilities rather than confirmed service.
