Friendly staff, everything went smoothly. Gluten free snacks would would be the cherry on top!

We have always flown with Alaska when we can. As they have great customer service. This trip we had to transfer to Air LINGUS in Denver to go to Dublin. That’s where things went bad! Our checked luggage didn’t arrive. The process to make a claim was way more complicated than it should be. It took 5 days to recover our luggage. The whole time we couldn’t talk to a real person who could tell us anything. The whole time Alaska blamed Air lingus and vis a versa. No one seemed want to help us. That was the worst part.

I'm a platinum member with American Airlines, however, my ticket did not display status and thus I did not board with an early group. I traveled with my two daughters and we were given a row of seats that did not recline. Not the treatment I would have expected for a platinum customer. The flight was also a bit late leaving Portland. Also on my flight to Portland we were not given premium seats. In fact, we were in the last row of the aircraft.

I was at risk of not getting on the flight, as when I presented my boarding pass at the gate, it showed me as not having checked in. I was sent to the desk as the last of the other passengers boarded. The agent there said he could see that I had done all of my part and allowed times recommended, but it showed me as not checked in and he couldn't figure out how to correct it. He actually asked them to hold the flight as he struggled with it. He called for support, someone corrected it, and he printed boarding passes for both flights to reduce further issues. I did get on, and needed to ask someone to exit my seat.

We had a birthday one day off and almost missed the plane Our fault

5 hour delay from Portland to Newark. Boarded and then were told we had to get off and wait five hours for flight. No food vouchers or any other compensation because they said it was an air traffic control issue. Plane is bare minimum like a discount airline. They have free entertainment but you have to get to it on your own device no screens in the seats

Alaska app and website had numerous problems so couldn’t get boarding passes or check seats

Very good. Gate personnel were excellent flight attendants were also able to change my seat at the last minute everyone, courteous, polite, and.

It was horrible. Last minute gate change, delays, more delays and then we had to wait for a stweardess to onboard. No explanation for the wait. No apologies. We got to RDM way past schedule @ 1:30 am!!!! Stressful and exhausting. We'd avoid flying Alaska ever again.

On time, smooth take off and landing, efficient boarding. Gate staff excellent, stewardess grumpy, but civil enough.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

It was delayed instead of departing at 9:20pm, we departed at 11pm… putting us in Columbus after 2am! It was awful. Had I known about the delay, I could have spent some time in the United Lounge… I was starving because I started my journey in Budapest… so I was exhausted and hungry. Plus I had to make new arrangements to be picked up at the airport in Columbus, instead of midnight it was 2:30 am after getting luggage and out of airport. Not feasible. I would have just stayed in Chicago for the night and gotten a morning flight.

Not a great experience. We paid for the upgrade for premium economy seats and seated ourselves in very comfortable seats. Someone came along with the same seat on their boarding pass. The aircraft had been changed and as a result we were booted out and sent further back to small uncomfortable seats. After complaining we were moved to emergency row seats, which gave us more leg room but the seats don’t recline. For people in our 70’s we found having to sit upright from California to NJ very uncomfortable. Not sure why they chose to move senior citizens instead of the two people that were allowed to take the more comfortable seats. Not happy.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

The food should improve! And The flight should leave on time and not make the traveler wait.

It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

A little bit more leg room in premium economy. I am 6’4”.

Overall it was good. I missed my connection but I was put on another flight.

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Overall very good, only complaint I have is the crew from CLT to SAT could have collected trash sooner.

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

Initial flight was cancelled at the time of arrival to the airport, flight alternative requires switching from direct to flight with a layover, and the plane felt like it would split apart, it was so rattle-y.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

Flight was delayed again and again ultimately almost three hours getting us to our location at close to midnight by the time we got in and out of airport to destination. I had taken time off work to enjoy an evening at destination and that was now wasted

AA re-routed flight from HNL to LAX due to delay. My group of 3 with reserved seats in row 9 was broken up, with one assigned to a middle seat, another in the last row of the plane. Not happy. No explanation to the delay. No apologies. No compensation. Would have been nice to be offered an Admiral Club admission or a voucher for the extra 3 hours of layover in LAX. Could not hear the boarding gate announcements in LAX. Adjacent gate was boarding at the same time. Loud speakers were competing against each other. Barely made my boarding group.

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.
