Agent boarding us in San Diego lectured me on showing up on time for the flight, and said that if I had been three minutes later, he would have denied myself and my wife boarding. Our trusted traveler numbers were not in the system, even though I entered them when I bought the tickets. Our food orders were not in the system, even though I entered them prior to the flight. My wife requires a wheelchair, and that was delayed on both flights.

Staff at Gate desk were helpful. My connecting flight from the first part of my trip Kona to Seattle was late. I had to run through SeaTac Seattle to catch my flight to San Jose. They made an exception to let me board. On my return trip San Jose to San Diego and San Diego to Honolulu the same thing happened. One flight arrived late and I had to run through the terminal to catch my connection. There are no Gluten-free & Vegan options meals and snacks to purchase.

Very pleasant , a flight attendant Jo did a great job mixing me up a beverage and just brightened the trip .

Spent 30 minutes in tarmac bcoz arrived earlier and crew nit ready for us. Told that the airport is being renovated so limited arrival space. 6 hours flight should have not two snacks but one major meal.

Flight attendant was rude when I advised her that the bathroom had no paper towels or tissue paper.

Departing flight to San Diego was delayed. Return flight from SD to SBP was delayed. Not terrible but not ideal

Good leg room, no problem with overhead storage and the staff was super helpful.

I purchased the internet during the flight and it stopped working after 1 hour, so I barely got to use it.

Good experience, although it was a little cramped being a tall person. Otherwise everything went smoothly and professionally though

Big delay of over 7 hours on next leg of trip with Alaska. Would have been nice to have food or something

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.
