Very comfortable - thanks. Only small criticism was the delay in disembarking caused by the passengers in the front two rows chatting to the cabin crew.

Very comfortable - thanks. Only small criticism was the delay in disembarking caused by the passengers in the front two rows chatting to the cabin crew.

Probably one of the best flights I’ve had! From entering the airport, to boarding to landing.

My as.com flight was too short to care (Tucson to phoenix) or comment.

It was a little chilly on the ride. The entertainment was the book I brought, and it was excellent.

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.

Nothing! I just didn't eat or use entertainment. I had three seats all to myself and it was wonderful!!!!

The confusion from Alaskan Airlines to American, no one at the front desk of Alaskan told me I didn't have a flight, which made me miss my flight that was transferred over to American TERRIBLE customer service at Alaskan!! American Airlines was a great experience. Alaskan TERRIBLE!

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

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Newer plane, relatively easy boarding, not a full flight and was told that we could not be moved up because of weight and balance issues. Otherwise, a very good experience.

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.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?
