What to check before booking
Allegiant Air is worth comparing for nonstop US leisure flights, particularly where alternatives require a connection.
Route and connection
Check flight frequency and the airports at both ends before committing to a fixed itinerary.
What the fare includes
Compare the same cabin and fare conditions on each itinerary. Check seat selection, changes, refunds and the total price after any extras you need.
Baggage rules
Add cabin bags, checked bags and seats to the base fare to see the real total. Check the allowance on your booking and Allegiant Air’s official website before paying and again before departure.
Three checks that save time
- Confirm the departure and arrival airports, local times and total journey length.
- Identify the operating airline on every segment and allow a practical connection margin.
- Add bags and seats to both fares, then compare the final price and change conditions.
