C
5.3 Fair
Pros:The price was unbeatable, especially if you don't pay for a checked bag, carry-on, or a soda on the flight. Very smooth flight as well.
Cons:The plane interior looks like it was gutted, then fitted with hard, plastic seats. No headrests, no privacy for the flight attendants. Everything costs extra.

2.0 Poor
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.

Cons:the seats are hard and very narrow.
B
6.0 Okay
Pros:The crew was very nice.
