The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

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.

They did not let my husband on the plane with our service animal at the last minute. Do NOT fly this airline with a service animal!

The non-stop flight from Grand Rapids was excellent. I neither expected or needed a budget flight and Allegiant made the trip easy and for an affordable price, Arriving at the Mesa Airport (AZA) is a delight compared to the international airport. For our return flight, we were able to arrive 75 minutes before the flight, return the rental car, check our bag and make it to the gate in plenty of time. That would never happen at most airports.

Actually, for the price, I'm willing to put up with a little discomfort (upright chairs) and at times inconveniences (like any airline), lack of entertainment (I can bring my own). My flight was non stop and smooth. I would fly this route again.
