Flight on time. Crew good. Seating Bad. Have to pay extra on a not cheap flight to avoid being next to toilet.

Both of my planes were delayed which is less than ideal but it's alright, unsurprising with very small flights.

Excellent, I traveled with my adult mom, she was happy for your service, especially, because you helped her with the reel chair. Only a little thing, in the airplane to Boise, the seat was very worn.

Everything was great, your crew is always very pleasant. Your airplanes are always so cold though.

I appreciated that the staff went out of the way to make sure I was taken care of.

I had a horrible and traumatic bullying experience the last time I flew ( frontier). I was incredibly anxious about these flights. However, it was so relaxed, organized and the crew was efficient and polite. It was so refreshing and relaxing.

Didn't care for the crowding at the gate area at SEA TAC. Not a fault of the airline.

I recently flew with Alaska Airlines on a trip to Oregon and had a very frustrating experience that I hope the airline can learn from. I purchased upgraded seats with extra legroom for my flight, paying the additional fees for the comfort and space. During my trip planning, I called customer service to inquire about their pet travel policies and conditions, as I was considering bringing my dogs. However, I ultimately decided NOT to bring my pets and never authorized or confirmed any pet travel arrangements. Despite this, Alaska Airlines took it upon themselves to change my seat assignment without any notification or contact. When I arrived for my flight, I discovered that my paid upgrade had been downgraded to a regular seat - presumably because they assumed I would be traveling with pets based on my inquiry call. I hope Alaska Airlines will improve their communication processes and ensure that customer inquiries don’t automatically trigger booking changes without explicit customer authorization. Better staff training on distinguishing between inquiries and actual bookings would prevent this type of situation in the future. While I appreciate that the airline tries to accommodate pet travelers, making assumptions and changes without customer consent is poor service that needs to be addressed.

Flight was delayed and hour due to tire issue. First flight of the day, this issue should have been discovered prior to boarding.

I am mobility challenged and ground crew were accommodating to my needs. One must walk up a ramp to board Alaska planes. Terminal to tarmac to ramp to plane.

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.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water

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.
