This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Service was professional and quick. Premium economy seat was comfortable given the class

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Crew was great! Good meals. Had room to stretch out

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

It was so much better than expected, Ohare is not such a pleasant experience but American Airlines with the new, clean aeroplane and free Wi-Fi was outstanding and the crew so pleasant and helpful.

This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

Was put into a seat right behind the toilet that had no entertainment possible but did have plenty of leg room over noisy part of plane.

The seat when "flat" was not flat and pad was too thin to cover it.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Flight: Started on time. Comfortable flight. Arrived on time. Crew: Very cordial and helpful. Drinks and snack was served with a smile. Overall enjoyed the trip. Regards, Hari Doss Chanchala Doss

To have arrived on time and not 3 hours late after having already spent $100 to change to an earlier flight, only to arrive back home close to the original flight time.

American Airlines is a miserable experience. It is predictably miserable, in the sense that every time I fly American, I brace myself for the certainty that it will be unpleasant and uncomfortable. But it is unpredictable in the sense that I never know if the flight will be on time or delayed nine hours (both happened to me this week). I never know if I will be able to sit in the seat that I selected when I purchased the ticket or if I will be told by Customer Service (!!!) that I must relocate from first class to a seat in the back of the aircraft with no explanation (both happened to me this week). Will the food be frozen and half defrosted, or scalding hot? Will the drinks be warm? Will the flight attendants be surly and mean? Will the toilets be cramped and foul? Will the seats be narrow and uncomfortable? Will there be a real electric outlet at the seat, or just an unreliable USB-2 port? Will there be enough seats in the boarding lounge or just a few? Will the boarding process be smooth and efficient, or will the gate agents mess it up and delay it needlessly for 30 or 40 minutes? Will the catering and cleaning crew be prompt or will they take an extra 30 minutes? Will the brakes on the aircraft work properly, or will the pilot delay takeoff for four hours while the ground crew attends to what can only be described as routine maintenance that should have been done the night before? I've eexperienced every one of these unpleasant things this year, 2026. The only thing I can reliably count on is that American will find a new way to make the experience of flying as miserable as they possibly can.

Wifi was spotty. Tray table was very dirty when I sat down.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

I flew four flights on British Airways within two weeks. I was unable to download the boarding pass to my phone for any of the four flights. I could check-in for my flight but the system would not give me boarding pass. I tried multiple ways and multiple times. I discovered many other passengers also had the same issue with their boarding passes. No explanation or acknowledgement by BA.

Lovely big plane. Excellent take off and landing. Cabin crew were so nice. Flight in time no delays

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!
