Pros: Lady moved us closer to the front of the plane
Cons: Flight was delayed over 5 hrs, Poor communication, lazy flight attendants that don't smile, I was the first one in the bathroom on the plane and it had pee in the floor and seat, no complimentary items for the delay, no apologies un til the pilot came on when we boarded. Won't fly frontier ever again.

Cons: I tried to cancel this trip but was told I would have to pay more in order to receive a refund. Very disappointed customer as I have traveled with Allegiant many times and the one time I try to cancel my flight, I’m told I have to pay a fee which was more expensive than the actual price of the ticket. Waste of money.
