It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

Seats were very uncomfortable and being charged for snacks and water.........

Crew was great. No entertainment and food and beverage was for purchase only, even water

The plane had originated in Las Vegas at 6:30 in the morning and flew to Moline where we boarded. The flight left around 12:30 PM and there were no boxed snacks available and many of the alcoholic beverages were unavailable. I would find it hard to believe that that many of the passengers coming from Las Vegas at 6:30 in the morning, drank and ate that much of the items. I can only come to the conclusion that someone failed to stock the plane for the round-trip. This is a huge revenue failure for the airline and disappointment for the passengers. The flight crew did not seem happy to be there and did not engage with passengers. Allegiant you can do better.

The worst flying experience ever 3 delays. No accommodations. Had to deboard the plane after being delayed.

I love that I can fly straight to Phoenix/Mesa on Allegiant without any layovers! I bundled my flight to include a couple of different perks, one being I got to pick my seat. I initially picked my seat, and then a week before I flew out, I got a notification I had to pick my seat again, which I did. When I got to the airport, I realized I still didn't have a seat assignment and needed to have the gate agent assign me a seat. What was the purpose of bundling if in the end, I didn't get to pick my seat? Also, bundling didn't include a carry-on so I ended up having to pay $33 extra for that so what would have been a $59 flight ended up being almost $180.

I did not go on my trip. I requested a refund and still have not received it.

I went to lower my tray table and it was very nasty. Looks like some one had left some food on it and then just closed it up.
