We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We were unable to land in Liberia. It was not the airline’s fault, but we had to be diverted to SJO.

We had things stolen from our luggage, we also were refused an upgrade on a flight that was not full.

When we left, it wasn't Great . People were drinking heavily, very disrespectful Extremely loud, the entire trip. I think the crew members, should have get their attention. Coming back was great.

I sat in the club. The seeds were fantastic. The meal was great and Entertainment was good. The crew was fantastic. I recommend it to everybody.

The food was small portions and not fresh. I was seated at the back of the plane so by the time the cart approached me most of the food options were sold out. The cabin crew was fantastic however.

Great flight and crew. Food isn't free and neither are headphones...

We were in economy class but paid for option Plus which offer you an extra snack after take off, free earplugs & blanket. The crew were very attentive. The comfort however wasn’t great, hard to be comfortable in such restraint place. Wasn’t able to sleep through out the 7hrs flight and was exhausted upon arrival.

The flights were on time and the crew was friendly and helpful. The food was ok. The seats were quite cramped and if the seat in front was tipped back there was very very little room. The entertainment was only on your own device and there was no usb charging

Boarding and staff were excellent. The food was ok. Very cramped seating. No existent entertainment other than on iPhone over wifi with poor choices of movie or shows. Bring your own entertainment. Nowhere to charge your phone

Delay was not properly communicated. Service, plane, value of ticker were all great.

There were several issues with this flight. I have flown quite often internationally and I was surprised by the lack of presence of attendants other than meal and drink times. The food was not best but I feel that is the norm. We also had to get off the plane once in London via stairs and bus to the terminal. Anyone who had another flight had to then get another bus to another terminal. This causes me to miss my flight and have to rebook.

The boarding process was a nightmare and though we were traveling business class, we were in Group 2 and the organization was terrible. The Business Class on this flight was crowded and did not feel clean and nice. Overall, I would not travel Business again on the American Airline flight through British Airways Not nearly special enough for the considerable cost .

The luggage was completely damaged. It was ripped at the corner and the lock was stuck. We had to rip it open.

Not too impressed with them to be honest. They had forgotten my gf meal, despite the fact that the app had notified me that it was sorted. Apparently there is a ‘glitch’ in the system, according to one of the stewardesses, and has been for a while. Also the legroom in economy is way too small (and I’m a slight person) and are very uncomfortable. An extra Internal flight I booked via the app, had not even given me the option to order a meal, so was unaware of that and left without food on a 9 hr. flight !! Don’t think I’ll use AA again after this.

3 hour delay on run way, not even a drink offered, staff seemed rude and rushed, felt unwell so asked twice for paracetamol and was told to wait, never got it

Due to the long delays and rescheduling boarding was horrible. However, the gate staff and the flight attendants went above and beyond to remedy our frustrations. They were able to handle every potential harsh situation with Grace, compassion and coolness of head. Kudos to the MIA Gate A12 and night crew of flight 1572 YYZ to MIA.

I liked nothing about this particular flight. Not only it was initially delayed for two hours due to late arrival of the plane, but the flight attendants were also very late to show up coming from a hotel (based on the announcement made by the gate agent). They did not arrive on another late flight, so why couldn't they be on time? Total disrespect of the passengers!! The plane itself was cramped and the seats super uncomfortable. To top off the poor experience, my video screen did not work. To summarize: flight delayed for 3 hours, cramped and no entertainment (for me).

They kept posting delaying flight due to maintenance issues from incoming arrival flight since 10am, the flight is supposed to depart at 3:45pm, after kept delay until 12am, they finally said it’s canceled. What were they doing for the last 13 hours? After 2am, they still don’t find hotel where we can stay. terrible experience!

not enough crew for business class and not great service as a result. underwhelmed overall

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

Super. Planes were clean. Flights were on time. boarding was smooth. Flight attendants were professional.

ground crew at Casablanca as well as at Montreal was not helpful at all. specially at Montreal airport, very rude .

The flight attendants were lovely - very warm and kind. Really appreciated it.

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

eveythink, because of you I lost 100 euros for my train connection

There was a terrible delay upon arrival in Barcelona. The plane had to park a great distance from the terminal, and only one bus was available to make the ~15 minutes each way trip, meaning it was ~ 45 minutes after we landed that I finally entered the terminal.

Cold frozen fruit for breakfast was unexpected and a waste in my opinion. How about a warm bun would have been better. Otherwise great on time flight.

I used to enjoy the travelling experience, but no more. We pay more and get much less. No air travel for me on the near future.

The TSA people or whatever you call them were a bit rude- I asked why I had to take my shoes off bc I'm 75 and in the USA, I don't have to. The man didn't need to snap at me. It wasn't even busy! The plane was ok, a bit small for such a long flight, but I'm very familiar with the 737 used ( I fly it often between SFO and SAN) service was ok-nothing special. If I drank alcohol I guess I would be happy with free choices. the plane was HOT and even the FA commented on it. They tried to get it cooler, but it never happened.

The Q400 plane is getting old and very noisy. They should allow the quieter jets fly onto the island.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

The flight was delayed and I was stressing the whole time about whether I would make my next flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

The flight crew did a good job, the main problem I had was in the layout of the pod itself. I know it does not matter but the connection for the head phones was not A- easy to find, B- very difficult to do based on the placement ( behind the right shoulder, very hard to reach, the type of plug on the frame vs the actual plug of the headphones), C due to the location and the way it connected, it did not allow me to use my own headphones, D- very low quality and very uncomfortable headphones, E- Surprisingly, very old selections of movies, for me, at least. I will still fly with Lufthansa as you deliver a very good product overall and I enjoy the quality of service, the ease and the prices. Thank you.

Ground crew at checkin in Hyderabad airport was terrible, they seem to be intent on being a pain to passengers. Folks made a huge fuss about size of backpack and made me rearrange contents to make it fit in the sizing slot. All for a flight that is 60-70% full.

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever

Crew had connection details for only 2 other flights and gave less than empathetic guidance.

I thought that the seats in Economy were ok. The attendants were very nice all the time. But the pasta for dinner was pretty awful. I am not sure why the boarding cannot start earlier in such a big plane. It’s pretty lame to start boarding 30 minutes before the scheduled departure and then blame the delay on the runway traffic.

Missed our flight to London and we were put on coach seats to Munich.

Nice flight. Legroom was good. Food was good. Staff was friendly and helpful. Plane was modern and clean. Seats and headrests were comfortable. Entertainment system was good and modern, with a bright LCD screen and many appealing choices.

If they wouldn't have canceled the flight WITHOUT informing me until I looked at my ticket and saw I had 2 extra layovers in 2 different cities than the ones I paid for? That would have been nice.

I have something to say about the flight I took from London to Gothenburg, after my flight from Austin to London. I fly a lot and have done so for decades. I first flew to Scandinavia in 1973. My former wife is Norwegian. The main thing was the experience at the Gothenburg airport. Three flights from Britain arrived around the same time. So there were huge lines at immigration since Brits are no longer a part of the EU. After over an hour in line, I finally gave my passport to the immigrations man. You’d have thought I was an Afghan. I just barely got into Sweden. I had to answer all kinds of blunt questions. I had to show all kinds of onward tickets, addresses of places I’d be staying and it was pretty daunting. Perhaps it has to do with the situation with Russia. British Air might have done something to prepare people that things have changed a lot and they’d better be ready to run the gauntlet when trying to get into the country here. Thanks for listening and taking this into consideration. Sincerely, a senior citizen of the USA

Poor BA get a lot of stick and have some problems getting your bags to the same destination BUT the whole experience is very much 5 star and probably due to excellent, helpful and sooo British staff. We travelled in economy plus.

I didn’t receive my luggage until day 5 of a 9 day trip. During a layover a crew member made a very insulting comment about where I was visiting and where my partner was from in England.

Attitude of crew could be more friendly and less stern and instructive.

The luggage is still in transit and the ground staff at Heathrow airport very rude and uncooperative. If I was you, I would fire them straight away. Bunch of incompetent folks.

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

I liked BA land team for boarding, the food, entertainment should be considered to be improved

My flight was late. We stayed in aircraft one hour 😩
