Airline reviews

I loved that the checking in process was seamlessly easy and user friendly. The crew was very nice and professional. Unfortunately, we were seated in the back of the plane across from the bathroom. There wasn’t much room for leg room and comfortability. Alongside, we had to listen to a baby crying up and down the aisle way for the entire plane ride. The turbulence of the plane landing was rocky. Overall, the experience with Alaska was just okay. We made it home alive so that’s always a positive.

would have been nice for flight to not be delayed by 2 hours so that we had to pay $80 to get home since BART had shut down. i thought a 10pm arrival would leave enough time to account for delays but i was wrong.

One of the best roundtrip flights I’ve ever been on. We needed assistance for my elderly mother and without fail, each and every Alaska team member was helpful, kind, and patient. Will fly Alaska again and again.

As always to close confinement for passengers not in upgrades. I like that you still get carry on and personal bag.

I had a negative experience, the flight delay was very long, I didn't like it

The seats in first class are very dated and quite uncomfortable. I don’t need lie-flat seats for a 6 hour flight, but more recline is really necessary.

One of the stewardess, Tre, went above and beyond to ensure my comfort!

Passengers were not informed timely of delays. The staff appeared like they didn't really care about the passengers.

Flight was delayed for weather, then delayed for mechanical, then just cancelled. Once mechanical problems started I wish you had just started offering rebooking options (at the same airport). I felt my trip was not a priority for you. I called you, I asked for a better option (than changing airports), then I had to literally run around the airport making it happen. Do better.

always delayed. toilet is too stinky worse than smells in sf homeless distriction

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.

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.

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!

Tight! Seats are not designed for those of us who wear extra-large clothes.

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.

Easiest flights I’ve ever taken. Plane was comfortable without overly crowded seating.

Terrible. Still have not received the refund from them. They sent it to some account that I don't even know. Spoke with costumer service and they are unable to help.

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.

Good, but a bit late on take off after loading. Don't like charging for carry ons!

First time flying with them and will definitely fly again in the future. Crew was so nice and friendly, fought was seamless. They are simple planes, no entertainment, but it’s fine for a short flight or if you have personal devices Rates are competitive, and they did so well with keeping the flight on time after a tropical storm, where other airlines had delays and cancellations.
