Poor|Oct 2021

The check-in process couldn't have been worse. Besides they have no customer service to speak of, I wasn't able to purchase a 2nd checked bag prior to the trip, the app just wouldn't let me no matter what. I spent over an hour on hold waiting for a rep who wasn't able to help me. At the airport we politely asked the rep to help since we were unable. She flatly refused to do anything. When we asked to speak to a supervisor she said she was one of the most senior people there and if "We're still not happy she can give me a number to call where I can wait on hold for over 2 hours to be told the same thing I'm telling you now." Absolutely atrocious. First and definitely LAST time flying Allegiant.

Nothing

The $17.00 i paid to insure the flight was not honored. I had some health issues and needed to cancel. I was then told that the airline I chose through your site, won’t honor it. I am furious and am owed my refund.

Wonderful|Nov 2021

I think regular soda and water should be covered. Also the leg room isnt good. But it would not matter if the seat was adjustable.

Mediocre|Dec 2021

30 min to get luggage at SRQ! This not what we are paying for.

Mediocre|Mar 2022

The boarding was ridiculous. They were off on the number of infants on the plane and it delayed us by an hour. It was really frustrating and they only updated us as the very end.

Poor|Jan 2022

Tried to check in on line and I could not do it. Because I had minor kids with me. We were separated in our seats. I had to pay airport prices for my bag going back to Rockford I was not a very happy camper.

6.0

Okay|Nov 2021

This flight not too much to like. .5lbs and they were gonna charge us $50. No one on the flight had a personality. Literally they all just stood there with a frown on their face. My 3 year old who is always cheerful spoke to all the ladies and they all just said hi in a somber tone. Very disappointing. Got charged for two drinks when paying with my Allegiant Mastercard. Should have gotten one free. Just a disappointing flight experience.

8.0

Very good|May 2022

The seats are small and hard. There are zero frills whatsoever. Everything you can think of costs extra. Beyond that we were surprised at how uneventful and easy the flight was. We only spent 3 hours on the plane (Boston to Florida), if it were more than that I might look elsewhere for a bit more comfort...

8.0

Very good|May 2022

There is no food offered, not only are you not allowed carry on luggage with your flight but the checked in luggage is 10 pounds less than the traditional 50 pound limit. That is very disappointing and certainly compromises the value of the discount pricing.

6.0

Okay|Jan 2022

The crew was great. seats were small. Plane was late both going and coming. Waited both times upon arrival to get to a gate. Not too bad on arrival to Flint. Worse at Punta Gorda. No entertainment on board, but didn’t expect any. The flight itself once we got in the air was good.
