Allegiant Air—often searched as “Allegiant Airlines”—is a Las Vegas-based, low-cost carrier built around nonstop leisure travel. Founded in 1997, it began scheduled service in 1999 and often links small and mid-size U.S. cities with vacation markets such as Florida, Las Vegas, Phoenix, and Myrtle Beach. The network changes by season, so the best destination for you depends on your departure airport and travel dates.
Quick Answer
Allegiant Air serves more than 110 U.S. cities with nonstop routes, many of which operate only on selected days or during certain seasons. Use Allegiant’s interactive route map, enter your home airport, and confirm the exact airport code and dates before booking. Allegiant Air’s own network remains domestic, while acquired Sun Country continues operating separately for now.
Key Takeaways
- All Allegiant Air flights are nonstop; the airline does not sell one-stop or connecting itineraries.
- Routes vary by departure city, travel date, and season, and many do not operate every day.
- Popular destination markets include Las Vegas, the Orlando area, Phoenix/Mesa, Fort Lauderdale, Myrtle Beach, Nashville, and several Gulf Coast cities.
- Check the airport code carefully because Allegiant often uses secondary airports such as Orlando Sanford (SFB), Phoenix-Mesa (AZA), and St. Pete-Clearwater (PIE).
- Compare the full trip price, including bags, seat selection, ground transportation, and schedule limits—not just the base fare.
How to Find Allegiant Airlines Destinations
The fastest way to see where Allegiant flies from your city is the airline’s interactive route map. A general destination list can be useful for ideas, but it cannot tell you whether a nonstop flight is available from your specific airport on your preferred date.
- Choose your departure airport. Enter your home city or airport code on the route map.
- Review the displayed nonstop routes. Allegiant does not build connecting itineraries, so only direct routes from that airport will appear.
- Check active and seasonal service. A route may run only during summer, winter, holidays, or a few days each week.
- Search your exact dates. Allegiant typically publishes schedules six to nine months ahead, and available flight dates appear in the booking calendar.
- Confirm the airport code. The marketed city name may refer to an airport outside the city center.
Note: “No flights found” does not always mean Allegiant has left a market. The route may be seasonal, may operate on different weekdays, or may not yet be loaded for dates beyond the current booking window.
Allegiant provides scheduled nonstop service from more than 110 U.S. cities, but each origin has its own limited route list and flight calendar.
Allegiant Airlines’ Domestic Destinations
Allegiant’s published airport list covers more than 100 airports across the United States. Its direct-route model connects regional communities with leisure destinations rather than sending most passengers through a traditional hub. The current passenger fleet includes Airbus A319 and A320 aircraft plus Boeing 737 aircraft.
The examples below are current destination markets shown on Allegiant’s official airport list. They are not available from every departure city, and some routes are seasonal.
| Destination market | Common Allegiant airport code | Best known for |
| Las Vegas, Nevada | LAS | Shows, dining, nightlife, and desert day trips |
| Orlando area, Florida | MCO, SFB, or MLB | Theme parks, family resorts, and the Space Coast |
| Phoenix area, Arizona | AZA or PHX | Desert hiking, golf, and warm-weather trips |
| Tampa Bay, Florida | PIE | St. Petersburg and Clearwater beaches |
| Fort Lauderdale, Florida | FLL | Beaches, boating, and South Florida access |
| Destin/Fort Walton Beach, Florida | VPS | Gulf beaches and family vacations |
| Myrtle Beach, South Carolina | MYR | Beaches, golf, and family attractions |
| Nashville, Tennessee | BNA | Live music, food, and nightlife |
| New Orleans, Louisiana | MSY | Creole cuisine, music, and historic neighborhoods |
| Bozeman or Glacier Park, Montana | BZN or FCA | Mountain scenery and outdoor recreation |
Why the Exact Airport Matters
Allegiant sometimes markets a broad destination area instead of the nearest major airport. Orlando service may use Orlando International (MCO), Orlando Sanford (SFB), or Melbourne Orlando (MLB). Phoenix service may use Phoenix Sky Harbor (PHX) or Phoenix-Mesa Gateway (AZA). Tampa-area flights commonly use St. Pete-Clearwater (PIE).
Warning: Do not book a hotel, rental car, cruise transfer, or theme-park shuttle until you confirm the airport code. Two airports marketed under the same destination name can be many miles apart.
Does Allegiant Airlines Fly Internationally?
As of July 31, 2026, Allegiant Air’s own published route map and airport list show a domestic U.S. network. The original claims about Allegiant flights to Cancun, Puerto Vallarta, San José del Cabo, and San Juan should not be used to plan a trip because those destinations are not listed in Allegiant Air’s current branded network.
| Network | Current status | What travelers should do |
| Allegiant Air | Domestic U.S. destinations on its published route map | Search and manage the trip through Allegiant |
| Sun Country Airlines | Includes select international markets and remains a separate carrier in the near term | Book, check in, and get support through Sun Country when the flight is sold by Sun Country |
| San Juan, Puerto Rico | A U.S. territory, not a foreign country, but not listed on Allegiant Air’s current airport page | Do not assume a route exists; verify the operating airline and airport before booking |
Note: Allegiant Travel Company completed its acquisition of Sun Country Airlines on May 13, 2026. The companies said both airlines would continue operating separately in the near term, with their own brands, reservations, check-in, customer service, and rewards programs.
Best Destinations for Families with Allegiant Airlines
Orlando is the leading family choice because the area offers major theme parks, water parks, resorts, and attractions for different age groups. Check whether your route lands at MCO, SFB, or MLB before arranging transportation.
Myrtle Beach is a strong option for families that want beach time, mini golf, shows, and casual dining. Destin/Fort Walton Beach and Gulf Shores work well for a slower Gulf Coast vacation. Fort Lauderdale can suit families combining beach days with other South Florida activities.
For the easiest trip, choose a destination with a nonstop route from your home airport, a flight schedule that fits school or work dates, and ground transportation you can arrange without a long transfer.
Top Destinations for Solo Travelers with Allegiant Airlines
Las Vegas is easy to explore alone because entertainment, dining, museums, and tours are concentrated in a well-known visitor area. Nashville offers live music, museums, food, and walkable entertainment districts. New Orleans is another strong choice for travelers interested in food, music, and historic neighborhoods.
Solo travelers should pay close attention to late-night arrival times and the distance between the airport and lodging. A low fare can lose its value if the only practical transfer is an expensive taxi or rental car.
Allegiant Airlines’ Destinations for Adventure Seekers
For mountain trips, check routes to Bozeman (BZN), Glacier Park/Kalispell (FCA), Missoula (MSO), or Boise (BOI). These markets can provide access to hiking, skiing, rivers, and scenic drives, though the best activities depend on the season and local conditions.
For desert scenery, Phoenix/Mesa offers hiking and day-trip options. Provo (PVU) can work for travelers heading into Utah’s mountain and outdoor areas. If camping is part of the trip, this guide to tent camping spots near you can help with trip ideas after you confirm your flight route.
Outdoor destinations often require a rental car, advance permits, weather planning, and extra baggage. Check the airline’s rules before packing skis, golf clubs, or other sporting equipment.
Allegiant Airlines’ Destinations for Beach Lovers
Allegiant serves several beach-oriented markets, including Fort Lauderdale (FLL), Destin/Fort Walton Beach (VPS), Gulf Shores (GUF), Myrtle Beach (MYR), Key West (EYW), Sarasota/Bradenton (SRQ), and St. Pete-Clearwater (PIE).
The best choice depends on your departure city and preferred trip style. Myrtle Beach offers a busy family resort atmosphere. Destin and Gulf Shores focus on Gulf Coast beaches. Fort Lauderdale provides broader South Florida access. Key West offers a smaller island setting but may have fewer route options.
Allegiant Airlines’ Destinations for Foodies
New Orleans stands out for Creole and Cajun cooking, neighborhood restaurants, seafood, and live music. Nashville combines hot chicken, barbecue, modern restaurants, and music venues. Charleston and Savannah/Hilton Head offer Southern food, historic districts, and coastal flavors.
Food-focused travelers should check whether the return flight operates on the needed day. Allegiant’s limited weekly schedules can make a two-night food trip easy from one origin but impractical from another.
Hidden Gems: Lesser-Known Allegiant Airlines Destinations
Traverse City, Michigan (TVC) offers access to Lake Michigan scenery, wineries, and seasonal outdoor activities. Boise, Idaho (BOI) combines a compact downtown with nearby trails and day trips. Gulf Shores, Alabama (GUF) is a newer beach-market option for some origins, while Asheville, North Carolina (AVL) offers mountain scenery, arts, and food.
These smaller markets can be excellent values, but service may be highly seasonal. Confirm both outbound and return dates before reserving lodging.
How to Choose the Best Allegiant Destination
- Start with your origin. The best destination is one Allegiant actually serves nonstop from your airport.
- Match the trip to the season. Beach, ski, and mountain routes may appear only during peak demand.
- Check the airport-to-hotel distance. Secondary airports may save airfare but add driving time.
- Compare the full schedule. A route that operates twice a week may force a longer stay than planned.
- Price the whole trip. Add bags, seats, transportation, parking, and lodging before comparing airlines.
Tips for Booking Allegiant Airlines Destinations
Compare the Total Price, Not Only the Base Fare
Allegiant uses an unbundled fare model. The base fare may not include a full-size carry-on, checked bag, advance seat selection, or other optional services. Compare the final checkout total with competing nonstop and connecting options.
Pro Tip: Price bags during the original booking. Allegiant states that bag reservations are cheaper when purchased in advance than at the airport.
Know the Current Baggage Limits
Under Allegiant’s current baggage policy, one personal item up to 7 x 15 x 16 inches is free. A paid carry-on may be up to 9 x 14 x 22 inches. Standard checked bags must weigh less than 50 pounds and measure less than 80 linear inches. Fees vary by route and when the bag is purchased.
Check Flight Days Before Reserving Anything Else
Some Allegiant routes operate only a few days per week or during one season. Search both directions before paying for a hotel, rental car, event ticket, or cruise. Allegiant says schedules are usually published six to nine months in advance.
Plan Around a Nonstop-Only Network
All Allegiant flights are nonstop, and the airline does not sell connecting itineraries. If your city does not have a direct route to your chosen destination, you will need another airline, another departure airport, or separate self-booked tickets. Separate tickets add risk because one airline is not required to protect the other booking after a delay.
Verify the Operating Airline After the Sun Country Acquisition
Allegiant and Sun Country remain separate carriers in the near term. Use the airline shown on the ticket for booking changes, check-in, baggage rules, customer service, and rewards. Do not assume the two route networks or loyalty programs are already interchangeable.
Use the App for Trip Management
The Allegiant app and mobile check-in tools can store boarding passes, show trip details, add bags or seats, and provide flight-status notifications. Mobile check-in opens 24 hours before departure.
