Tickets we booked together in January became two different connecting flights. VERY PISSED a about this and a terrible start to our bucket list vacation

Could not check in online - had to get boarding passes at the ticket counter and our daughter got bumped off our connecting flight. NOT OK!

I needed more space to sleep on an overnight flight.

Our flight time was drastically changed which caused us to lose a day of vacation

Wonderful respectful staff for a short flight late at night...lots of considerations all met!

Flight was delayed which led to missed connection, but rebooked on a more direct flight at the last minute and arrived in Juneau on time with all our luggage. Little stressful and our family seating got split, but it all worked out in the end.

Only issue was the 2 hr delay after an 8 hr layover. Very long day.

Very bad, terrible food and late by 2 hours. Then no to open aircraft doors

Flying on Hawaiian Airlines was good. But, getting a boarding pass was a hassle. I booked what I thought was an Alaska Airlines flight that was actually a Hawaiian Airlines flight. I couldn't check in online. I had to wait for the Hawaiian Airlines counter to open so I could get my boarding pass which was a requirement for me to get in The Club or the Centurion Lounge. (I had no check in luggage so I didn't expect to have to physically check in.) The Alaska Airlines staff blamed the FAA for the problem.

Terrible check in experience, and they ended up losing our bag.

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

Food was surprisingly good but the WiFi was not great

Was on time until within 1 hour of flight-how does that happen? Staff very friendly.

Weather delay in Chicago?. No sense of urgency to make connection in Chicago for our connecting flight that wasn't delayed. Connection was missed.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

I learned that seating towards the end of plane that a line forms for the restroom and people use your chair as a hand railing, bumping your seat consistently. I was seated in the aisle. I think that next time if I am towards the back row I would want to sit in the middle or window seat.

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.

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

Flight was delayed and after being in the airport for like seven hours, it was canceled.

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

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

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!

We started with trouble checking in 24 hours early. Then my husband did not get his TSA precheck. Finally flight delayed due to no crew. I know things happen

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

It’s a great flight. Service is good. Staff is awesome.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.
