As great a red-eye flight as red-eye flights can be.

Once boarding started it was pretty quick. Food was inedible; cold and salty..

Entertainment kept turning itself off. Gave up on watching a movie.

Both the WIFI and entertainment did not work for 2.5h

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

They are always late and seats was also not having working charger

Broke my luggage and I can't get a resolution yet.

My flight to London from Philadelphia was cancelled due to weather.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Not comparable to Qatar Airways services on flights to Doha. Flight attendants provided basic services; I was never recognized by name or as an Executive Platinum member. Restrooms were not kept clean during the flight.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

So, the trip from Dublin to LA did not really happen because the flight took off before we could finish the transfer.

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB flight

I was not admitted to the flight!!! i need a refund for this.

Well, I think we left close to on time. Crew was “eh”.

Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

Great setup on both flights except the last flight we got condensed dripping all over me in the last 20 mins of the flight

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

I waiting for 2 hrs to retrieve my luggage. Didn't get home till 3am.

The flight left late and I didn’t get a glass of bubbly upon boarding (which I’m used to when booking business class on other flights), but otherwise it was a pleasant flight with lovely, helpful crew members and I enjoyed my meal.

Flight cancellations, delays, mass confusion and disorganization! That’s Air Canada for you, nothing new. I would have chosen a different airline if it were an option, and Air Canada continues to prove they don’t care about their customers.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Couldn't fit knees, only 1 toilet working, didn't get anything to drink cause the stewards were not able to get to us

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even

Our Jackson, Mississippi to Dallas Fort Worth flight was delayed on 1/19/26.. This was changed to Jackson to Charlotte in the last minute because of this delay. This started some kind of disconnect between American Airlines and British Airways bookings. We could not go past the passport control in London Heathrow. I had to go to the counter and waited for more than 30 minutes to get a new boarding pass. Problems did not end there. Somehow our entire return flight was canceled by someone. I had to make several phone calls over several days to fix the problem – this was not easy from India. Looks like there was some kind of disconnect between two airlines or some agent did not do it right. I’m anxious to know what went wrong.

The issue was not with BA it was with the link yoiu sent fopr booking the flight

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Getting the boarding passes between the BA and AA apps was very clunky.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.
