It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

This was the first flight in the morning. We boarded fine. The cabin door was closed and we were ready to go. We were notified by the Captain that ATC issued and ground stop for 40 minutes. So, without even pushing back from the gate, we were already 40 minutes late. We actually were released to push-back and taxi at 30 minutes. But, some passengers had tight connections and were not going to make their connections. Some passengers asked about the delay and the effect on the connections and were told by the cabin attendant that all flights will be delayed and so they should be OK. However, that was not true. My connecting flight was on time and I arrived at IAH with 21 minutes to make my connection. I did and I'm happy about that, but the flight crew should not have given assurances to the passengers who might have missed their connections.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

It was better than excellent. The staff in Mason City were great. The young woman that pushed my wheelchair did more than could be expected of her. She came from India 17 years ago. I don't remember her name.

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

All good flight was 35 minutes early when arriving in Edinburgh

Flights were on time actually early service was good and crew cheerful

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

The boarding timing needs to be improved. The flight was delayed again because it took way too long to board. I was already exhausted from sleeping at the airport and spending all day there due to delay from my previous flight that connected in Chicago.

Everything was excellent and I enjoyed myself. Thank for everything

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Boarding was quick and efficient. We arrived at our destination early.

I'm not sure American is capable of on-time arrivals and departures. When you land at ORD, you almost always get held on the tarmac because your gate is still occupied. I may have missed my connection, but that ended up up being significantly delayed as well. Once again, I finally got home well after midnight.

Same plane as RDU to LGA — internet not working. Pilot issue of some sort at end of prior flight - I was on same plane for my connection. Late/delayed —

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

I didn't go from Reno to Phoenix I ended up going from Reno to Dallas to Tucson because my flight rebooked because my Amtrak was late I tried notifying you guys I also don't know what you ask me about my flight because you guys didn't book my flight

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Nice aircraft. Good crew. Delayed departure from Houston, but arrived on time in London. Main thing I don’t like about flying BA is having to transit through security in London Heathrow. A major pain!

BA code for a Vueling flight. All god but the temperature in the plane (too hot when engine not running but otherwise ok)

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Wish the food and overall service was better. They treat Business class passengers same as economy

Food options limited and quality wasn’t very good. I was I was in premium economy and the people in front of me pushed their seats back to fully reclined position which made it difficult for me. My seat wouldn’t recline at all. I suggest that BA restrict the recliner more. Also, the audio in my headset didn’t work unless I held it in all the time. Entertainment choices were good. Customer services is excellent. Thank you to BA team.

WiFi wasn’t available to economy until the end of the flight.

Very good staff members with sincere passion and responsibility in their job.

We paid for Business Class seats, but system did not have us and they were not available.

Very please with the seating that the Kayak staff booked for us!

Worth every penny to upgrade to BC. Treated and felt more like First Class
