Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

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.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

Great. No choice for n/a. No food or entertainment options

just had water and there was plenty of leg & seat room. But then i don't weight 220#s!!

Not totally their fault- screaming kids that had zero parent intervention.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

I didn’t like it at all. I miss my second flight because of the delay on Allegiant Air now I m stuck in MCO.

My TSA number was missing from my ticket which shouldn’t have happened since it’s in my file. The on board flight attendant who was a male, did not want to help me put my luggage in the overhead bin and made a very rude comment and was very unpleasant. The good… the woman who fixed my ticket with the TSA number was excellent and I had extra legroom which was perfect.
