The flight got delayed. They forgot to bring the drinks when I asked for it. The toilet is messy.

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.

Thanks to a delay of an hour of my flight to Philadelphia on American Airlines I missed my connecting flight to Amsterdam. On arrival at Philadelphia he crew on the delayed flight did not ask the passengers to let connecting passengers get off first and I arrived a few minutes after boarding was closed at the original time for the flight to AMS, this despite the fact that I had received a message from American Airlines that departure was delayed by 25 minutes. Overall very poor service, no effort from the part of American Airlines to accommodate the passenger, just rebook the flight for the next day.

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 liked my seats on the return trip. Didn't like having to pay for luggage on an international flight. Also didn't like that it was on American airlines and not British Airways. I specifically selected a BA flight to experience that airline.

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.

My luggage was lost at the airport but American Airlines contacted me and got it to me the next day.
