Absolute nightmare dealing with British cancelled flight and then having them rebook me with American, their "partner" company. Spent three hours this morning dealing with these two unprofessional companies and their lack of communication between each other.

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!

Equally friendly crew and experience. It was complimented by the time we got to spend in the fantastic KLM lounge while we waited for the flight.

Announcement was made that flight was delayed for at least two hours and that delay might be longer or might be cancelled. Desk staff specifically said they would not help rebook until the 2 hour delay had passed. I bought a ticket on Delta amd actually flew to London.

This seems like an old plane. Poor quality of screen to watch movies and very small selection of movies. No charging spot to plug and charge our phones. This was a long trip and these two elements are important to make the trip enjoyable.

My seat was comfortable, with good head and neck support.

BA doesn't allow guitars as carry ins, unlike most every other overseas carrier. That's a major negative for me, and I've spread the word to other musicians who will avoid the company. Terrible policy.

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.
