The staff were professional. Boarding was orderly. The flight was smooth. The lavatories were clean.

As a tall man, even with an entire row to myself, it was impossible to be comfortable. I had to fold myself like origami to fit. My head and neck was pitched forward, even with the seat back reclined. You got me, next time I’ll spring for business class.

The flight was very pleasant, with great service. The in-flight entertainment selection was good, food was tasty. The day we flew, this flight was maybe half-full in coach, which may not be great for BA, but fantastic for leg room! The attendants were lovely, and I particularly enjoyed the continuous water service through the flight, which kept me nicely hydrated. The ice-cream mid-way through movietime was a welcome treat!

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.
