The return was painful because of the flight that was canceled. Nobody was able to help us out. It took hours and a lot of walking on two different airports to get a new flight

The return was painful because of the flight that was canceled. Nobody was able to help us out. It took hours and a lot of walking on two different airports to get a new flight

I can’t even the whole trip was a catastrophe

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

Delay more than hour created pressure to catch the connecting flight

I purchased a one way business class ticket from Geneva to Miami but the check in agent said I had an economy ticket and later upgraded to business class. This was not the case, I had a single business class transaction. I was forced to pay for my second checked bag. I am unsure of why this happened. But I won’t use Kayak again for business class tickets.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

The food was good. Most the staff was pleasant. The flight would be drastically improved with WiFi on a long international flight.

The whole experience was positive. Crew very friendly and helpful. Very greedy with pre-seat allocation. Web site too complicated

Each flight we took was late with little or no updates or information.

Swiss airline do not allow online check-in before 24 hrs, this is very inconvenient to us. I tried many ways such as booking code(6 numbers) or 13 booking numbers , neither of them work, Lufthansa is better which allow us to check in even before 30 hrs, so we can assign our seats( not many people want spend extra money to assign seats on top of airfare which is already spent.)

Flight was delayed. Though I checked in with BA live chat three times, our special meals were not provided.

My experience with British Airways is excellent, thanks for all 🫶🏻✈️

Old tired plane, Uncomfortable business class seat. Breakfast dreadful and meagre. At least flight was on time!

Safe arrival. Improvement on Time efficiency Effective Communication will be great.

The crew is very friendly and helpful. The food is good for airplane food. The flight is long and hard to sleep. The leg space is great. The plane arrived in plenty of time.

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

They removed our booking without telling us. Cost us thousands to book last minute

Enjoyable flight, helpful crew everything was organized to accommodate passengers.

Captain sick. Unable to get replacement so delayed me 30 hours, many others delayed 54 hours. TOTALLY DESTROYED ALL MY PLANS, including lost my rental car which would now cost over 5 times what I paid so stuck with buses n trains... lost hotel reservations.... HORRIBLE!!!

The international flight from PHL to Lisbon was one of the worst I’ve experienced, ever. What was really disappointing was the entire experience of comfort and service in the coach cabin after takeoff. The food was inedible and the wine served with dinner was such low quality - it tasted of petrol. I couldn’t eat more than a bite or two of the chicken entree, being worried it would make me ill. The service took so long to reach the entire coach cabin, I ended up having the lights turned off on me as though I had to rush though dinner (though as I mentioned, it wasn’t as if I ate much - only the salad). Most of the attendants seemed generally annoyed and were not friendly or polite. While there was some turbulence, it wasn’t too uncomfortable and I know that is just a chance. The temperature of the cabin was so warm, even a friend a row or two up and on the other side of the plane felt like this. To top it all off, the seat was so uncomfortable and flattened/overused, I had back pains for DAYS afterward.
