Allegiant Air is a U.S. low-cost carrier built around a simple idea: connect smaller and mid-sized cities directly with popular leisure destinations. Founded in 1997 and based in Las Vegas, Allegiant operates scheduled and charter service and focuses heavily on nonstop vacation travel. That model can produce low base fares and convenient routes, but it also comes with extra fees and limited flight frequencies on many city pairs.
Quick Answer
Yes. Allegiant is operationally reliable by several important measures, especially cancellations and baggage handling. It ranked second overall in The Wall Street Journal’s 2025 airline scorecard and first in The Points Guy’s 2026 reliability category. The main tradeoffs are weaker punctuality than some rivals, add-on fees, and limited backup flights on many routes.
Allegiant’s business model is different from that of a large hub-and-spoke airline. It mainly links travelers in smaller markets directly with leisure destinations instead of building itineraries around connecting hubs. Its current route map states that Allegiant flights are nonstop and that the airline does not sell one-stop or connecting flights.
That simplicity removes some connection-related failure points, but it creates another issue: some Allegiant routes operate only a few times per week or seasonally. A cancellation may therefore be uncommon yet more disruptive when it does happen.

Safety record and incidents
Incidents and concerns
Questions about Allegiant’s safety reputation largely trace back to its former McDonnell Douglas MD-80 fleet. A 2019 U.S. Department of Transportation Office of Inspector General report examined FAA oversight of maintenance issues at Allegiant after a series of MD-80 engine shutdowns, aborted takeoffs, and unscheduled landings.
The report found weaknesses in how FAA inspectors documented risks and evaluated corrective actions. That history is relevant, but it describes an earlier period of Allegiant’s operation and should not be treated as a direct description of the airline’s current fleet.
Improving safety measures
Allegiant retired its final MD-80 aircraft in late 2018 and moved to an Airbus A319/A320-family fleet. It has since started another fleet transition, adding Boeing 737-8-200 aircraft while gradually retiring older Airbus jets.
As of the end of the first quarter of 2026, Allegiant reported 17 Boeing 737-8-200 aircraft in service alongside its Airbus fleet. Its first-quarter fleet plan called for 25 737-8-200s by the end of 2026, although the airline notes that delivery and retirement plans can change.
Commitment to safety
Like other U.S. scheduled airlines operating under Part 121 rules, Allegiant is subject to FAA certification and continuing oversight. The FAA’s Office of Air Carrier Safety Assurance is responsible for certification, surveillance, investigations, operating procedures, crew qualifications, and maintenance oversight for Part 121 operators.
Note: An airline’s operational reliability and its safety record are not the same thing. Cancellation rates, on-time arrivals, and baggage handling measure service performance; FAA oversight and accident or incident investigations address aviation safety.
Customer satisfaction and reviews
Passenger opinions about Allegiant vary because the airline offers a very different product from a full-service carrier. Travelers who value a low base fare and a nonstop flight from a smaller airport may see strong value. Travelers expecting a carry-on bag, free seat selection, frequent departures, extensive loyalty benefits, or premium onboard amenities may be less satisfied.
Online reviews on platforms such as TripAdvisor and Yelp include both positive and negative experiences. These reviews can help reveal recurring pain points, but they are self-selected and should not be treated as a statistical measure of airline reliability.
A more useful booking decision combines recent operational data with Allegiant’s published fee structure and the schedule on your specific route.
Note: Compare the final checkout price rather than the advertised base fare. A cheap ticket can become less competitive after adding a carry-on bag, checked bag, preferred seat, priority boarding, or Trip Flex.
On-time performance and reliability
Allegiant’s recent operational results are much stronger than its older reputation suggests.
In The Wall Street Journal’s 2025 U.S. airline scorecard, Allegiant finished second overall. Its cancellation rate was 0.55%, the lowest among the airlines ranked, and it also performed especially well in baggage handling. Allegiant separately reported a 99.89% controllable completion rate for 2025, a measure that excludes disruptions attributed to factors such as weather and air traffic control.
The Points Guy’s 2026 Best Airlines Report, which used 2025 Department of Transportation data for its reliability analysis, ranked Allegiant first in that category. The analysis considered on-time performance, cancellations, mishandled baggage, mishandled mobility devices, and involuntary denied boardings.
Allegiant’s strongest reliability advantage is flight completion: it posted the lowest cancellation rate in The Wall Street Journal’s 2025 scorecard and continued to have the fewest cancellations in the Journal’s mid-2026 review through July 13.
There is an important caveat. Allegiant did not lead the industry in every operational metric. The Wall Street Journal’s scorecard showed stronger punctuality from other carriers. In other words, Allegiant has recently been very good at operating the flights it schedules, but that does not guarantee that every flight will arrive on time.
Pro Tip: Check both the airline’s overall reliability and the schedule on your exact route. A route with one Allegiant departure every day or two carries a different recovery risk from a route with several daily alternatives.
What happens if Allegiant cancels your flight?
This is where Allegiant’s limited-frequency network matters most. A low cancellation rate is reassuring, but travelers should still plan for what happens when their particular flight is canceled.
Allegiant’s current Contract of Carriage, effective July 21, 2026, says that when scheduled transportation is canceled, the passenger can generally choose transportation on another available Allegiant flight, a refund for the unused transportation including applicable taxes and ancillary fees, or a credit voucher.
Allegiant’s flight-disruption guidance also explains that the airline does not normally make reservations on unrelated airlines for disrupted passengers. That can matter on a route where the next Allegiant departure is not until the following day or later.
Warning: Avoid scheduling an Allegiant arrival immediately before a cruise, wedding, international connection, prepaid tour, or other event you cannot miss. A buffer day can be more valuable than the savings from the lowest fare.
Fleet and maintenance
Allegiant is in the middle of a major fleet transition. Its 2025 Form 10-K reported 79 A320s, 28 A319s, and 16 Boeing 737-8-200 aircraft in its operating fleet at December 31, 2025. By the end of the first quarter of 2026, the airline reported 17 737-8-200s in service.
Allegiant placed its original Boeing order in 2022 for 50 737 MAX aircraft with options for 50 more, marking a major change from its Airbus-focused strategy. The first 737-8-200 was delivered in September 2024.
At the time of the order, Allegiant said the new aircraft were expected to burn approximately 20% less fuel than older Airbus A320-family aircraft while carrying more passengers. That figure should be understood as the airline’s fleet-planning estimate rather than a guarantee for every flight or operating condition.
The Airbus fleet remains important during the transition. Allegiant’s 2026 fleet plan still includes substantial numbers of A319 and A320 aircraft while additional Boeing jets arrive and selected older Airbus aircraft are retired.
Sun Country acquisition
Allegiant completed its acquisition of Sun Country Airlines on May 13, 2026. The closing is confirmed both by Allegiant and by the U.S. Government Accountability Office.
The deal gives the combined company a broader leisure network as well as Sun Country’s charter and cargo operations. For passengers, however, the integration is not complete.
Allegiant’s current FAQs state that travelers cannot yet make a single booking across Allegiant and Sun Country because the reservation systems remain separate. Regular Allways Rewards members also cannot currently earn Allways points from Sun Country flights or redeem Allways points for Sun Country travel. Sun Country continues to operate separately during the integration period.
Note: The acquisition is complete at the corporate level, but that does not yet mean Allegiant and Sun Country function as one airline from a passenger’s booking or loyalty perspective.
Routes and destinations
Allegiant’s route network is designed around nonstop leisure travel. Instead of concentrating most passengers through large connecting hubs, it frequently links smaller communities directly with destinations such as Las Vegas, Phoenix/Mesa, Florida beach markets, Nashville, and other vacation-focused cities.
In a July 14, 2026 announcement, Allegiant described its current network as 566 routes across 124 U.S. cities. The total can change as seasonal routes start, stop, or return.
The airline’s unusual city pairs are one of its biggest strengths. Travelers in markets with limited nonstop competition may avoid a connection entirely. Allegiant’s earlier strategy of connecting regional airports such as Evansville or Fort Wayne with leisure markets illustrates the same model.
Another 2026 change is distribution. In July, Expedia Group became Allegiant’s first authorized online travel-agency partner under a 12-month exclusive agreement covering Allegiant’s full network. Travelers can therefore encounter Allegiant inventory through Expedia Group brands as well as Allegiant’s own channels.
The airline’s leisure focus can also complement broader trip planning, whether travelers are researching popular vacation destinations or other destination guides.
Pricing and fees
Allegiant’s low advertised fares come from an unbundled pricing model. The ticket covers the basic transportation, while travelers choose whether to pay for several optional extras.
According to Allegiant’s current Optional Services & Fees schedule, one personal item that fits under the seat is free. The listed maximum personal-item size is 8 x 14 x 18 inches.
Allegiant lists carry-on baggage at approximately $10 to $75 per segment depending on route and purchase timing, while advance seat-selection prices can range from $0 to $80. Checked-bag prices vary by route, and Allegiant advises purchasing bags before arriving at the airport because airport prices can be higher. Fees and ranges can change, so the checkout price for the actual itinerary should always control your comparison.
The maximum published carry-on dimensions are 10 x 16 x 22 inches. Standard checked bags can weigh up to 50 pounds before overweight charges apply.
Warning: Do not compare Allegiant’s base fare with another airline’s final fare. Add every bag, seat, priority option, change feature, and other service you expect to use before deciding which ticket is actually cheaper.
Loyalty program and perks
Allegiant’s current loyalty program is Allways Rewards®. It is free to join and awards points based on qualified spending rather than distance flown.
According to Allegiant’s Allways Rewards FAQ, members generally earn 1 point per qualified dollar spent on Allegiantair.com and 2 points per qualified dollar on eligible Allegiant itineraries with qualified spending of $500 or more. Taxes and certain fees do not earn standard base loyalty points.
Points can be used toward eligible Allegiant purchases. The program is simpler than the large global loyalty programs offered by network airlines because Allegiant does not have the same international alliance structure or extensive premium-status ecosystem.
Following the Sun Country acquisition, ordinary Allways Rewards earning and redemption has not yet been extended to Sun Country flights. Allegiant says its Allways Rewards Visa card can earn card-spend points on Sun Country purchases, but standard Allways program members cannot currently earn or redeem normal Allways points for Sun Country travel.
Customer service and support
Allegiant provides online self-service tools, phone assistance, live chat, and other customer-care channels. Travelers can use Manage Travel for many routine tasks such as changing eligible flight dates, adding baggage, choosing seats, or canceling qualifying itineraries.
Customer-service experiences can still vary significantly during storms, cancellations, holiday peaks, and other high-volume periods. That is another reason to complete baggage purchases, seat selection, and contact-information updates before travel rather than waiting until the airport.
For a cancellation or major schedule change, use Allegiant’s official Manage Travel and flight-disruption tools first. The airline’s current disruption guidance explains the available rebooking and refund choices for the affected itinerary.
Pro Tip: Add your current mobile number and email address to the reservation and enable flight alerts. Fast disruption notifications give you a better chance of acting before other passengers compete for limited replacement seats.
Allegiant’s response to COVID-19
During the COVID-19 pandemic, Allegiant introduced measures that were common across the airline industry at the time, including enhanced aircraft cleaning, face-covering requirements during periods when mandates applied, schedule adjustments, and added flexibility for affected travelers.
Those pandemic-era measures are now mainly historical context rather than a useful measure of Allegiant’s current reliability. Today’s booking decision is better informed by 2025–2026 cancellation data, current fleet plans, FAA oversight, present-day fees, and Allegiant’s current disruption policies.
Who should book Allegiant?
Allegiant can be an especially good fit when it offers the only nonstop flight between your home airport and your destination. It also works well for travelers who pack light, can avoid optional extras, and have flexibility if the schedule changes.
It deserves more caution when your trip depends on arriving by a fixed deadline. A traveler flying to a cruise departure, wedding, graduation, international connection, business event, or prepaid tour should look closely at how frequently Allegiant flies that route and what alternatives exist.
- Strong fit: Flexible leisure travel, nonstop convenience, smaller airports, light packing, and travelers who understand unbundled pricing.
- Less ideal: Time-critical trips, travelers needing several daily backup flights, people who require extensive premium benefits, or passengers who expect bags and seat selection to be included automatically.
Is Allegiant a reliable airline?
Based on the most recent verified operating data, yes—Allegiant is a reliable airline by several important measures. It ranked second overall in The Wall Street Journal’s 2025 airline scorecard, posted the lowest cancellation rate in that ranking, and won The Points Guy’s 2026 reliability category.
The airline’s biggest strength is completion reliability rather than industry-leading punctuality. Its simple nonstop network reduces connecting-passenger and connecting-baggage complexity, while recent baggage and cancellation results have been excellent.
The tradeoff is recovery flexibility. Because some routes are seasonal or operate only a few times each week, one canceled flight can create a much larger scheduling problem than the same cancellation on a route served many times per day.
For travelers who understand the fee structure, verify the schedule, and leave a buffer before important events, Allegiant can be a strong value—especially when it provides a nonstop route that larger airlines do not.
If you are considering flying with Allegiant Air, review the applicable airline rules as well as TakeTravelInfo’s terms and conditions.
