Crew was very friendly and helpful when needed. Excellent choice of movies/entertainment (for my personal taste). Overall a pleasant, smooth 7 hour flight.

Food was as decent as an airline meal can get. Seats were as comfortable as an economy class seat can get.

The new flight procedures informational film at the beginning of the flight (BA/Comic Relief)

The flight was to Heathrow which was not prepared to accept us at all. We waited 45 minutes in passport control. I expect BA to make sure the port of destination is prepared to receive its passengers

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
