I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Everything was pretty good. I would like to have more drinks (water) during four hours of the flight.

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

My flight experience was generally good, but the boarding process was stressful. I was pulled out of line at the gate during the photo ID check, and after being cleared, I was never given an explanation for the delay despite asking for clarification. This lack of communication was the only downside to an otherwise smooth trip.

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

After a 5 hour delay waiting at the gate (3 delays adding up) with no clear reason provided, we finally boarded flew 3/4 of the way to Toronto then were turned back to New York. As we neared New York, the pilot declared that it was his fault, something to do with timing and him not being allowed into the country???? How could the airline let his happen? They had hours to prepare and make sure they had a crew available for the flight! We ended up in Toronto a day late with no sleep.

Rode in a smaller plane and short trip meant no snacks, no free wifi or tv. It was only 30min flight so honestly wasn’t a big deal to lack these items.

We were forced to wait nearly 50 additional minutes before leaving the terminal.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Flight delay in lax which delayed our connecting flight to Copenhagen. Was placed on standby the following day and got delayed again at Scandinavian air. Bad bad counter service at ar Canada in Toronto by the name of Camilla who said that she was doing us a courtesy for even finding a earlier flight for us after we the customer are the ones being inconvenient by the cancellation of our flight. Btw, we are going on a tour. Air Canada is the worse

Perfect. On time and the weather was perfect so we came in a few minutes early.

The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.

Upset about cancel to St. John’s and no overnight accomodation

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Entertainment kept turning itself off. Gave up on watching a movie.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

Backpack should NOT allowed put in the flight bin , only put it under the seat. I can't find space put my carry on luggage!!! and I pay for it ! that was very bad experience

It was fine. Everything ran on time, crew was great.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

Announcements were unintelligible. Entertainment system was non-existent. Ground crew kept changing story for flight delay.

Amazing and light experience, boarding on time, crew is super nice, clean salon and special thanks for movies availability. Provided by United Airlines

Unfortunately, my experience was disappointing. The crew were not friendly or welcoming, which made the flight less pleasant. Our flight was delayed, and we almost missed our connecting flight because of it. To make matters worse, the gate number shown on the digital ticket was incorrect, causing unnecessary confusion and stress before departure. Overall, the lack of accurate information and poor customer service made this a frustrating travel experience.

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

No TV on the flight. The charging outlet was not working. No food, even a sandwich. The served orange was poor quality.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

Totally uninformed of the situation. Not yet sure about compensation. Highly disappointed.

The flight was almost an hour delayed causing me to miss my connecting flight, then the rebooked flight was delayed a couple of hours. They also left my suitcase in the rain for hours ruining some items I had in there. They also just blew off my complaint. It was my absolute worst flight experience of all time:

It was decent, there was no WiFi on the flight but the FA’s gave everyone a warning once we boarded the plane. Unfortunately it didn't give me enough time to download my entertainment content.

American Airlines was horrible! The layover flight to DFW was delayed with no clear communication and for us having to stay the whole day which led to staying a night in Dallas was comped with 2 $12 dollar vouchers and a crappy hotel. We missed a whole day in Tokyo for our honeymoon and stressed the whole 24 hours. We were supposed to leave at the same time the following day, but that was delayed hours again. And instead of letting the delayed flight go first, they let the flight that was scheduled ahead of us. American should refund us the day wasted in Dallas that should have been in Tokyo! We had lost out on paid events that we can’t get refunded. When we finally did leave, it was a good flight. You would think that was the only issue with American but we from the LAX layover, we were delayed 6 hours and were given a $12 dollar voucher that covered a drink only. The only communication we were given then was that because they were delayed in a prior flight we were delayed again. I don’t understand why it was only with American that we had such a bad time with! They have definitely left a sour taste in our mouths for our honeymoon! And then they did send an email saying we could have 2K miles…. For what? To be delayed into another day and miss our flight again?

The delay was not handled well and the offers to move flights and get travel credit was also not ideal.

Limited service due to turbulence, N/A Food and Drink. No entertainment

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Was a normal flight but it was delayed, and there wasn't an explanation.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.

We experienced an involuntary change of schedule. Had 1st class tickets from Fresno to Bonaire, put us in coach from Miami to Bonaire a few days later - terrible flight, try to get a refreshment , water or a meal and air. We will never be subject to that again. I'd rather fly another airline that honors 1st class. Adding insult to injury AA reimbursed my wife's ticket $106.66 for the change in seating, me nothing. Haven't heard back from Customer Service, don't expect to - it's only online, can't speak with a live person. So the difference between 1st class and coach for that portion of the flight is only $106.66? Really? I've flown Delta and United on the same route, will go back to one of them again.
