Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

leg space better than expected. two washrooms for one plane isn't enough.
Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)
Excellent, professional, actually on time which is rare for late flights. Decent food. I love the new neck pillows! Nice, simple upgrade from the old ones I wasn't sure where to put. I wish they would allow more time for rest. It's a red eye 7 hour flight and meal service was about 3 hours.
The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.
The tv monitor in front of my seat was not responding. The flight crew reset it and it still didn’t work.
Maybe add a seat trade app for flyers that didn’t get seats together
There's just no way to sit fully upright and comfortably in these seats. There needs to be 2 more inches of room, and that's not something that only one person on the flight needs - the whole flight needs 2 more inches of room. If that means you sell 6 less seats, so be it. It's too close for anyone. Forcing people to pay for "premium" economy just to get "barely enough space to breathe" isn't really an answer to that.
Boarding is very confusing. They have Line 1 and Line 2 and many many Boarding groups. Everyone lines up under those two lines long before they call zones. If you have a higher zone 2 like I did due to a Premium Plus ticket, it’s very awkward having to ask each person which zone they have. Extremely chaotic process. On board the flight attendants had no charisma whatsoever, even to us paying extra for an upgraded cabin. I asked for a chamomile tea after dinner (as no coffee or tea was even offered) and the FÃ said they didn’t have even though listed on the drink menu. Also, the mid flight service was entirely skipped which was a soup and sandwich combo. Supposedly had a variety of snacks mid flight too but those never materialized either. A few times I walked Back there, not a single flight attendant acknowledged me as they were all deep into their iPhones. I simply Wanted a glass of water since ZERO water runs were made on this 9hr 30 min flight.
Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.
Crew was great and responsive. Entertainment quit working with about 4 hours remaining on the flight. My seat cushion was broken.
Not very good , the stewardess were unfriendly and they don't like to be bothered. Cos was a night flight and they need to sleep.
British Airways staff are very polite and willing to help.
It was so bad it will be my last. Connecting flight gate agent closed the door in my face when i told her my husband is 30 seconds away (and we were running close/late because the preceding AA flight was slightly delayed. We had to be rebooked on a non-direct flight with an overnight layover in Phoenix. This is the worst experience ever and for no fault of our own. The flight we were trying to get on would not have been late if the gate agent allowed my husband to get there. It was senseless, cruel and very upsetting. I don’t understand why we were subjected to this.
This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable
Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.
The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.
Checked in the minute I was allowed and still wound up in group 8 for boarding.
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 .
Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.
The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...
We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude
Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.
Everything OK , except the plane left more than an hour late so I couldn’t participate in an excursion I had that morning in Brcelona
Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.
very good all round. staff, food, entertainment, punctuality all very good
The cabin crew were great very helpful and accommodating. We had a fellow passenger throw up next to us. The flight crew did an amazing job cleaning up and reseating us. We did question as to if he should have been let on the flight as his condition was likely self imposed.
online check-in was horrible and didn't work either way
Horrible. Paid for seats for my family. Iberia changed planes and never notified us that the seats we paid extra for did not even exist on the plane. We were randomly placed on the plane. Thankfully, we were seated together. Upon boarding, my youngest daughter was pulled from the line and they just arbitrarily changed her seat 7 rows back from the rest of the family. I had to wait at the gate while they tried to see us back together. One of the most uncomfortable small spaces on a plane I’ve ever experienced. When I called Iberia, they first told me that no mistake was made that the plane was never changed. Yet my receipt for my paid seats were for rows that did not even exist on this type of plane we were getting on. They said that they would reimburse my money and I would get an email, but I’ve never received any information or emails regarding a refund for the seats that I had paid extra for. Then when we arrived in Madrid, one of the pieces of luggage that we had checked in was damaged to the point that the handle that was stowed in to the luggage was broken off by the crew members handling the luggage. The crew on the plane was very nice, but as far as the rest of the experience, I would be very hesitant to ever use Iberia again.
They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update
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
Crew and service was excellent. My seat was super small and cramped! No leg room
I asked for antibacterial wipes three times and each time I was told they will bring it to me right away with nothing delivered. I finally went to the galley and was told you did not have it. In a post COVID world that is just wrong. The crew was very non compassionate to passengers asking basic questions about food. Very disappointing and makes me reconsider my routing for the future trips.
I was extremely stressed out with the delay of our flight, not because of the delay per se, but we weren’t getting any responses from the staff/crew as to what was going to happen with our connecting flights. I think if they were better informed, and in turn we were informed, we would be more at ease. Also, at the Newark security area, the scan machine detected something “foreign” in my crotch and behind area, I cannot believe that in 2024, these machines cannot differentiate between a sanitary pad and a dangerous object. The security officer who conducted the body search was really sweet and apologetic, and asked me if I would like to move to a private area and conducted the search thoroughly without making me uncomfortable, but it is clear that these machines need an upgrade for such issues.
Flight delayed at Newark by more than 1 hour. Weather was perfect. No explanation provided. This delay made me almost miss my connecting flight at Munich. Bags from all passengers from Newark were NOT loaded onto the connecting flight to Munich. Two days without fresh clothes.
I missed my flight because previous flights came in late. Customer service hard to find and could not reschedule for the same day. Many people appeared to be behind the customer service counter, but only one or two willing to speak to the public. No offer to find alternatives My experience frustrating Very bad
Lufthansa give one a safe and seamless experience from check-in to baggage pickup
Be on time. Constant delays, missed connections. No excuses. Weather was not an issue
Because of a thunder storm in JAX we spent more than an hour on the run way in the aircraft. The crew did not even offered water to passengers.
The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.
The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.
I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump
Cancelled flight minutes before boarding. Rescheduled flight was two days later
The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!
Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.
The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.
The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?
Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.
Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier
