Airline reviews

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Food options were limited which is absolutely embarrassing for a Flight of this size The staff did not come around as much and I am not accustomed to such poor service from American Airlines Drinks I believe were limited to soda and water

Was as expected. Good leg room on planes - much appreciated.

Smaller, regional aircraft limits amount of overhead luggage space. At least there were jetways at both BNA and PHL. First class food service was minimal with the usual assortment of packaged snacks (nothing creative) and no handiwipes. American tries to turn around aircraft too quickly without enough time to clean the planes. WIFI service did not include TV programming.

6 plus hour delay with no explanation. No wheelchairs to transport us on arrival. Very disappointed.

Food choice is limited, entertainment better than average, seat leg room terrible

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Late arrival due to gate being blocked by stalled truck

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

We truly had not one problem. Nive enough to receive an upgrade. Flight attendants were extremely friendly and cheeful. Gladly will continue to fly American.
