Terribly uncomfortable sitting. Worst I've went had. Flight attendants had no personality what so ever. Dreading having to fly with you again to get home.

Flight was very good, and early, great! personnel were nice. Bag charges were excessive $77 each way, not quite as represented before I reserved my airfare.

We fly allegiant pretty frequently from FWA and we are always impressed by the staff there. They are always so kind and helpful and as a customer you can tell they enjoy their job which I feel is rare these days. When we traveled on our of FWA to PIE on 11/19/2025 we encountered someone new (at least new to us). I wish I could remember her name but don’t but she checked us in and was extra kind and pleasant. Flights are not always a pleasant experience and the experience begins at check in. She made the experience great from the start and we appreciate that as customers of Allegiant Air.
