Pretzels are awful. Empty calories. There’s gotta be something else.

Crew was great, flight was uneventful (which is what you want!), would like media in the seat backs in all airplanes ..but all in all it was a good flight experience.

Unfortunately, an issue occurred where a delay impeded me from making my connection in LA. I couldn't get a flight home until 10 hours after my originally scheduled flight. Once I finally made it to DFW for my connecting flight, my next flight was delayed. I was supposed to be home on 12/23 at 9:00 p.m. I didn't make it home until 12/24 at 11:00 a.m. I was given the choice to either take a flight the next day or the flight that way 10 hours later. I wasn't given an option for a hotel if I stayed overnight. I was also denied the ability to go to the Alaska Lounge due to the delay. It was a very uncomfortable experience. The only seat I was able to get on the next flight was in a row where the seats couldn't recline. After an extended wait at the airport, this was very frustrating!

Paid for first class, but the flight attendant for first class did the minimum required. She really ever came to pick up the trash, and never asked if we needed anything. Every person had to ring for the flight attendants if they wanted any extra drinks. When I went back to use the restroom, she was just sitting on her phone.

We don't have food or entertainment on this flight. We were late boarding but then arrived in Yakima early. Kayak sent me a delay notice but we weren't delayed.

I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!

Flight crew had the courtesy to ask passengers from my first flight to allow those of us disembarking to go first so that we could make it onto our connecting flights. Worked like a charm. Both crew and fellow passengers working together for a better outcome for all.

We missed our connection to Portland and ended up having to drive.

Spent extra to choose my seat. Found a window available so grabbed it. They did not mention the row didn’t recline. Had over 5 hour flight stuck in a straight back chair. Traveling for funeral - needed to rest and couldn’t get comfortable (row infront of exit😒 should have realized but wasn’t thinking I guess).

You an Kayak offered travel insurance. I had to cancel are flights which I well say was easy an I got my money back. BUT not the travel insurance Kayak or X cover has keep the money. So why I never went on the fligt I cancel way early. I know one thing I'll never go to kayak again.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

I like in St George and prefer to fly out of CDC than SGU. Hopefully, they will continue the flights out of Cedar

Other then mechanical/ computer problem and 3.5 hours flight delay the flight was great. I guess that what happened when you fly an old airplane now a day.

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Coach seating is debilitating, neither my husband or I can walk the following day

It was NOT pleasant. Started from checking our luggage to the last time getting off the plane. The crew was not friendly, the food was horrible and the seats were too close to each other that I got a bruise on my knee.

Late departure due to large number of wheel chair patrons. Used to having a box of snacks to select from in comfort plus. The flight attendant just rattled off what was available and asked us to pick. Felt rushed and uncomfortable. Seat was great. Prefer having the screen on the seat in front of me instead of having to pull it up from the seat side. Lots of room for my carryon under the seat in front of me.
