Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.
Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.
Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!
Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.
Not really their fault, but a 4.5 hour delay is pretty brutal
we were delayed going into and out of Newark Airport by 3-4 hours each way. Excuses/reasons given were misleading. Weather was cited at first when there was NO weather issue. Turns out Newark had a shortage of staff and runway construction. United knew this and should have NOT scheduled flights when they know we would be delayed so long. I will avoid United and EWR airport at all cost going forward. Delta never looked so good.
Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.
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.
Flight was full, and would have preferred an aisle seat, but due to getting a late ticket ,the seat I had was adequate. The flight crew were very help full and hard working. Food and drink were excellent for the 11hr flight. Overall I was pleased with flight, and would recommend British Airways again.
More choices on menu. Seemed only thing offered was Scottish, and while that’s good for the Scot’s it doesn’t help the Americans who don’t like that food. And I really hate it when, during sleep time the attendants have a very loud conversation right over you. Lastly, I paid 5000 dollars for business class, and having to pay more to choose my seat early is really an insult. Seems greedy

The chicken adobo was a little too spicy but good otherwise. My personal opinion. Movie selection could be improved, too many horror movies. Could add a few more chick flicks! The flight was bumpy at times. We arrived a little early too! Flight attendants friendly.
Again flight was awesome except British Airways lost both gate checked luggage’s. Still missing
really bad they refused to check in luggages that I had purchased, even showing them the transaction receipt from british airways app the staff in miami was MEDIOCRE
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.
From boarding, to attention in flight, I couldn’t fault it.
Not having to check carry on bags when plane wasn’t full. (The told us it was)
I was in business class for the 8 hour flight where: 1. The WiFi did not work 2. The entertainment system did not work 3. We were told there were no hot drinks for the entire flight
I had an issue with the name on my ticket vs my passport name. I was very upset that the Iberia ticket clerk had no authorization to help me and I was left to fix it. It took 19 calls of persons promising to accomplish and not doing anything before I reached someone who helped me in 10 minutes. Two of them even hung up on me. I missed my original flight because of this. Terrible customer service.
The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.
My carry-on bag was taken from me when I boarded. It was checked through to London at no charge. It took a big of shuffling, but I was glad not to need to mind it until baggage claim.
Flight boarded three hours late for no reason other than someone made a huge error in crew scheduling. We missed our connecting flight in Madrid and got zero help from American or Iberian airlines on rebooking. We had to pay for a car to take us to the Madrid train station and pay for train tickets to Santiago. We never used our booked flight to Santiago. American claims I can submit the expenses but they are not obligated to cover them. Very frustrating.
Flight delayed Service could be better Iberia staff are not really friendly
They cancelled the flight)(they said bad weather but many other flights took off) and made us wait 5 hours in line to figure out what to do. We ended up making a new flight the next day on another airlines...I hope they honor giving us our money back
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.
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 payment system was not working so was unable to connect wifi the entire flight
everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.
I ordered short ribs for main course. It tasted sweet, really sweet. Horrible.
The screen didn’t work and I didn’t get the seat upgrade I paid $300 for. They were no help with that,
Paid $180 for seat selection, and selection essnt honored. Have to call for a refund.
My flights were great and the crew on them was lovely especially the London to Barcelona flight as Al & AJ were so amazingly nice. I wish they would be my crew always as they have the best customer service. Sadly both flights were delayed the first one from Vegas was because they clearly loaded the cargo wrong the plane was off balance making us 2 hours late. This made me miss my connection and sadly it was challenging rebooking while I was on the flight. I will never use Kayak again as there was no customer service number or live chat and you rebooked me on a flight 2 days later. I had my mom call BA to change it which she did after spending an hour on hold. This should not be so difficult. My second flight was an hour delayed due to not being able to disconnect the bridge from the plane but I did finally make it home.
The delay was not communicated via text and the person who helped with check in also didn’t inform me about the delay. I ended up missing my connection and it was a waste of 5 hours. The crew didn’t mention there would be someone at the gate informing of if I would be rebooked and there was no signage. Overall a very poor experience. The British Airways app was also very buggy, and didn’t work. I will avoid flying with British Airways when possible.
A little better than outward journey but mild chaos at the boarding gate because some people with boarding cards from connecting flights had cards which weren't recognised
The BA business class cabin is excellent,very comfortable for sleeping but the service could be improved.
Surly rude flight attendants. I ordered the chicken and was given a vegetarian meal with no explanation and no opportunity to change it. I tried to order another beverage and was told by the young humorless flight attendant to “wait”. And she never came back. The seats were very uncomfortable and cramped. The last time I flew British Airways was many years ago but I remember it was amazing and the crew were very charming. This was a terrible disappointment given the cost of the flight.
