One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

Pushing back flight and ultimately cancelling it after multiple changes and hours of delays. Comm were terrible as to what was going on and what options were available.

Even though we arrived early and checked in, for some unexplained reason, our bags were removed from the plane and put on the next flight. It took over 12 hours after arriving to get our bags.

Stewardess was not accommodating when I requested a second drink.

The morning calzone was less than impressive and we ended up with heartburn

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

Flight was delayed multiple times and rerouted to different concourses in the airport because of all of American's delays. App/boarding pass would not update with changed gate information.

Absolutely infuriating. I was flying standby to get home earlier after flying 4 times with American in 6 days. I was #2 on the list with seats near the front and middle, in addition to the 4 first class upgrade seats that came back into the pool. I am a Platinum member, have their card, and they put me in the 2nd to last row in the middle. No loyalty whatsoever and they lost a fan for life. There is reason people have negative comments about American and I am done supporting them.

Horrible - their gate agents do not care and loyalty means nothing to them. Planes are often late and you are left on your own. Oh, and WiFi - good luck!

Awful! We boarded and then sat on the plane for 50 mins before having to deplane due to a maintenance issue which should have been addressed before boarding. Then we had to change terminals as there was no other plane for us at the current terminal. Then we waited another 2 and a half hours to board again only to wait for 50 mins on the plane again for the snacks to be brought from the broken plane. And once we were on the flight we still only got the complimentary cookie and soda or water. No food vouchers provided even though we had waited over 3 hours for our flight.

There was a 6 hours delay in our departure. And yet, no compensation was offered. A company should be responsible for such a delay.

Little bit of trouble getting my KTN and pre-check status onto the ticket, but otherwise the counter staff were friendly and truly concerned to get it right.

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist
