Flying Allegiant Air: what to know
Bags: where the fare grows
The ticket price is only the start on Allegiant Air. A first checked bag runs Varies by route — lowest when added during booking, and a second is Varies by route. Carry-on: Paid — only a small personal item is free. If you know you'll check a bag, tell us when you enquire — we'll price the ticket with bags included, so the number you approve is the number you pay.
Changes and cancellations
Change fees apply (Trip Flex add-on makes changes free). Cancellation: Free within 24 hours of booking; standard tickets are non-refundable unless you add Trip Flex. The practical takeaway: if your plans might move, the cheapest fare class is often the most expensive mistake. Ask us to price a flexible fare alongside the basic one — sometimes the difference is a few dollars, and it buys you real options.
Where Allegiant Air is strongest
Allegiant Air routes its network through Las Vegas (LAS), Orlando Sanford (SFB), St. Petersburg (PIE) and more. Fares are usually sharpest where the airline flies nonstop and often, so hub routes are where deals show up first. Routes our travelers book most: Allentown to Myrtle Beach, Allentown to Punta Gorda and Allentown to St. Petersburg. You can also browse today's live deals across every airline we track.
- Pay for checked bags in advance when you can — the airport counter is rarely the cheapest moment.
- The 24-hour rule protects you: cancel within 24 hours of booking for a full refund on tickets bought a week or more before departure.
- Set a fare alert for your route — Allegiant Air fares on popular routes move several times a week.

Book on Allegiant's own site, be flexible on days (many routes fly just 2–4 times a week), and travel with only a personal item for the lowest total.
›Does Allegiant fly daily?
Usually not — most Allegiant routes operate a few days per week, so check the schedule and plan your trip around the available days.
›How much is a checked bag on Allegiant Air?
