The room for legs is adequate for a 6’ tall man and the flight was comfortable. The cabin is clean and the crew is very friendly and pleasant.

Worst first/business class I have ever flown after 75 years on planes. Barely acceptable seats, terrible food, uninterested attendants, unavailable WiFi. I’ll never fly this airline again.

Again, very smooth and all of the Alaska folks were great. They continue to meet all my needs.

The whole experience went smoothly with no hitches along the way.

My Alaska Airlines return flight, although worked out in the end, didn't start off well. The initial plane that my family and I boarded was grounded because of a mishap that happened to one of the engines and everyone on board had to disembark the plane. Thankfully we were accommodated with a another plane but our initial flight was supposed to have departed at 11 pm San Diego time for Orlando but instead we ended up leaving at 1:40 am San Diego time. All Passengers were informed that part of the delay was that the plane had to be inspected by the captain, the food had to be stocked and the individuals responsible for fueling the plane left for the evening and had to be summoned to return to fill up our. The Alaska Airlines crew at the airport and on the plane were awesome and apologetic. I know that the crew wasn't responsible for the mishap of the engine but I think in the future the airline should offer a complimentary drink or (1) item of food other than pretzels, nuts or chips to all passengers since we're not to blame for the extreme set backs. The airline in general is good and I recommend to all flyers.

Late leaving so threatened our connection in Vegas to Seattle. We did make up time and made our connection.

Dropping off of the checked bags took way longer than it should have. The agent for the pre-tagged and ready to drop off line was gone and didn't come back for about 15 minutes. The other bag check lines were barely moving. Agents were standing around and not much was getting done. Everything else about the flight was great.

Was late but $50 voucher was great benefit of the summit card.

See previous. It was the flight from Honolulu to Kapalua that was cancelled.

I truly appreciated the kindness and attentiveness of the staff and flight attendants. They did their best to be prompt with departure times to San Diego and back to New York! Alaska Airlines ... you are awesome!!

Superb. Staff great. Great flight. As with other airlines, seating too tight and restrictive.

There is not one likable thing about this airline. It’s starts with the deceptive pricing and continues through the whole flight. The worst staff I’ve ever experienced way over priced bags absolutely no food or drink (unacceptable and you should be embarrassed) the seats are cramped and uncomfortable there is no entertainment there is nothing about this trash airline that constitutes any amount of money. It’s worse than spirit and way more expensive it is disgraceful. Do not travel with Allegiant I repeat do not bother no matter what they say the price is it is never ever going to be the right choice I’m mind blown at how awful the entire experience was I’m embarrassed that I chose so poorly I cannot reiterate enough how beyond horrible this company and its staff are, not one person on this flight or at the airport is qualified to sweep up trash on a city sidewalk they should certainly never be given any job that requires a brain or manners or communication with human beings, what a disgrace to the human race. Your criminal chiselers and should be put out to pasture

Great flight. Friendly staff. Free snacks and drinks would be nice. I would love fewer taxes and fees added on.

My 90 year old father flew with me. He needed wheel chair assistance and is nearly deaf. The staff was amazing with him.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

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

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.
