we were late due to plane's late arrival at the gate and then there was a glitch with a button or something that had to be fixed and we waited for a tech to do that . The flight was very bumpy and totally not anything to do with the plane or crew. Just saying what was a bit miserable and kind of worrisome give then recent circumstances with the planes. Nothing fell off or onto anything during the flight of take off and landing so I count myself lucky to have gotten to my destination there and back safely. Thank you for asking

The reduced size overhead compartments were a surprise. They keep getting smaller and smaller while amenities keep getting fewer.

My flight was on schedule, ground crew looks overworked, flight crew was great but refreshments could be better. The plane was clean and fairly new. Seats were comfortable but leg room was tight.

My flight was delayed in Fairbanks by 45 minutes with no explanation. My next flight was delayed 3 hours in Anchorage then cancelled altogether. Alaska Airlines App was not helpful as it auto-booked me to reach home 2 days later than planed. And I had to fly back to Fairbanks if I wanted to continue with that change. The only real assistance I received was from the Alaska Airlines gate counter supervisor. She was able to get me home one day earlier. This was my 1st experience with Alaska Airlines and it will be my last.

I'm a tall guy. Fortunately I was able to find seating in the emergency rows that gave me a couple more inches of room. My return flight a few days later, I wasn't as fortunate. Very painfully and uncomfortable return flight.

I think the pilots deserve most of the credit, the flight was smooth and they got us to Denver in a major winter storm when many of the airlines cancelled on other people . Alaska has my loyalty- must have better more capable pilots. Was on 720 - Seattle- Denver. The crew was alright, one of the stewards was obnoxious about applying for a credit cards she went on and on about how much she used hers- it was over the top and a turn off.

Always reliable customer service. Especially, the extra care on a long flight back to the Mainlaind.

Good flight. Pilot kept us well informed and attendants did a great job. Negatives:,1) little snack packs are far too expensice; 2) arrived early but waited 1/2 hr+ to get to our gate to deplane!

Midway through the flight the stewardess moved a man from the back of the plane to the empty seat next to me, since I was sleeping I had not voiced a preferance either way. The stewardess woke me up to say I could move to the back of the plane if I objected to the man sitting next to me, at which point I simply asked "Why?" she was speechless and quickly returned to her duties. It was a strange encounter that seemed to make no sense, even now in reflection.

Great ! The counter staffs in Boston helped me to wrap my broken luggage with a plastic bag to prevent my stuffs falling out.

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

Crew were exceptional. Plane was quiet and quite empty, so I had a row to sleep across.

The seat could use more support or cushion. I'm in my 50's and have back issues so the seats are a bit hard for longer flights.

The plane was in bad condition. We were taxied for mode than an hour because a light panel had feel off. The bathroom in first class had broken panels as well. Overall poor aircraft maintenance

My only real complaint was how much turbulence there was-and that probably can't be avoided. I felt really sick getting off the plane. But boarding was super easy, the flight attendants were friendly, the bathroom was clean. Everything else about the flight was perfectly fine. Thanks!

Caroline (Supervisor) was great! Salute to the employees like her!

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.

Boarding was good, staffs on the second flight to Korea was invisible all the time. Water was only offered 3 times during a 15 hours plus flight. It’s absolutely not enough for such a long flight!

Traveling with delta is always a pleasure from the take off to the landing 🛬 🥰

Very crowded flight… a little disorganized.. why don’t they boatd the back of the plane first??

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

ticketing issues caused many customers to have to go back to check in after waiting in security, then go through security line again.

The seat was visibly dirty, had not been cleaned. I used my own wipes and they were dark after wiping down the chair and tray table.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

Lost luggage again. Our second trip to Mykonos, and 2nd time no luggage.

Flight was well orchestrated, made up time despite circling a bit all good on United. Travelers can just be so into themselves that common courtesy has gone out window for some, but that’s not on United.

Loading was quick and efficient. The bate and switch with discount tickets were you are forced to pay for bag.

Good flight, comfortable seats and very quick passage through Heathrow. Boarding in Washington was cramped and not well organized, but the rest was perfect.

Flight was delayed. Connecting flight left 5 people - pulled away from the gate 10 min early with no connection options until the next day !!!

Cons: "The original seats we purchased was a different plane. Only two in the row This plan was very crowded and no wiggle room to change seats"

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

Their computers were down upon arrival to the airport. They were unable to figure out how to board us. We were delayed over an hour and a half.

Delay. Flight was delayed in Washington.knew that connection was impossible as not enough time to switch terminals. The steward would not let me stay the night. So forced to Dallas.late night, after 10pm.hotel checkin was one hour. Passengers lined up only one girl to checkin at comfort inn. No food availability at that time. Had to leave early at 6:30 am to catch a flight at 8:45. Stressfull.

Despite a bumpy flight the pilot was great. The rest of the crew on the other hand couldn’t care less if a passenger would colapse and die. Horrible service, robot like, lifeless…

The experience with American Airlines was terrible from beginning to end. Flight 1210 from Cancun to Charlotte was delayed three times. AA customer service at the CUN airport could not provide information on why or how to accommodate me if I missed my connecting flight at CLT due to the delays. Upon arrival to CLT, de-boarding the plane was a horrible experience. You all should have allowed passengers with departing connecting flights within the hour, to get off the plane first! It caused so many passengers to lose valuable time waiting to get off the plane, and then the long lines in customs! American Airlines knew passengers had to make connecting flights and still chose not to hold the plane? I missed Flight 2758 from CLT to DCA for that reason. Waiting three more hours for the next - Flight 1269 from CLT to DCA. Once again another delay at the last possible minute before boarding due to the plane going out of service/maintenance. Once the new plane boarded, we sat on the tarmac for 40min. I did not arrive to DCA until 12:33am. I spent over 12hours at the airport and I plan to never fly American Airlines again.

No service due to turbulence. No entertainment on this type of aircraft. But nice old comfortable seats.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.
