Late BA flight made sure I had to wait 7 hours to catch and EVA air flight. I want my money back. I paid 1000 to flight British Airways not to be crammed on a flight as a show away. Super uncomfortable seat on EVA and a terrible experience. I fell on the plane.

Crew didn't reach middle of plane with Food & Beverage. Lots of fussy/serving of premium passengers but economy not really looked after. Was bashed into 3 times by same member of crew walking up aisle and not once apologised.

Seat pitch on the plane unbelievably cramped. When seats are so close that if you drop something on the floor you have to be a contortionist to get it, you know it's a problem NEVER fly the 787-900 economy.

Plane was old and dirty, seat pocket had junk in it. Seat was broken and couldn’t stay up. In flight movies were from few years back with a center tv and no head rest screen. Crew on overseas flights tend to be older in age and less tolerant..much better on continental on the same route.

1. Plane engine set fire while taking off... leaking fuel. 2. My bag fee was waived, but the next day after being grounded and put in a cheap hotel for the night, I was RECHARGED $100. 3. They knew my flight left at 9pm, still gave me ONLY 1 hotel voucher so I was kicked out of the hotel at 12pm with NOWHERE to go for NINE HOURS with 125lbs of luggage. 4. They provided a good voucher, but the cheap hotel they put me in didn't have a kitchen, USELESS. 5. The flight was LATE getting to London the next day and I missed my BRITISH Airway connecting flight to Thailand. Had to wait another 7 HOURS to get a flight out. 6. Terrible service, over priced and rude agents. The agent told me " I don't know who waived your fee yesterday, but I'm not." Cold, considering the plane I was on the day before was shooting fire about to explode. 7. I was rebooked no choice of seating or consideration.

From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew.

The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!

Flight way delayed 3 hours. Staff gave no information and wouldn't help rebook us onto other flights. They gave us food vouchers 2 minutes before we finally boarded, so we couldn't use them. The food on the plane had spoiled so we were all starving on the flight, and we all missed our connections. Horrible experience and wouldn't fly with KLM again.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
