After sitting on the tarmac (I understand the delay) for 2 hours there was no water available for another hour past takeoff. And then it was only available for purchase. Really, a cup of free water is asking too much?

On-time departure and arrival. Courteous efficient crew, both on land and in the air.

My main gripe is that if you want a plain cup of coffee or a bottle of water, you are charged for it and can pay only with a credit card, but only if that card is chip and pin, and my US card isn't. Yes, it is high time that the US move into the current millennium and get chip and pin cards, but that is beside the point. I also flew BA from London to Seattle (part of same trip) and the on-board meal & drink service was PHENOMENAL - the best I have had on an airline in years, and I did not get charged for anything, including alcoholic beverages. How can this be the same airline?

Short flight

All baggage lost. Wasn't put on the plane because they didn't have enough containers. Ground crew at London was courteous. Luggage had to be sent on to the US the next day. No free bags on this flight so all of the luggage lost had been paid for piece by piece. No free drink service; even a soda had to be paid for. No food, of course. Originating 10hr flight from Los Angeles to London was also uncomfortable, with small, packed coach seats, no air nozzles and poor headset connectors. I was very happy to get back on American Airlines for my return to Los Angeles. Wouldn't use BA again.

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

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 prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons 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 don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.

More questions or if you have a bad price to report to us
