-no communication -I stayed in 17 hours of cues -no hotel or meal vouchers -was not let out of the airport -no hydration in lines - people passed out -no line control, people were cutting and lots of arguments ensued -staff was not knowledgeable, was rude to angry customers -baggage was never returned to me, so I had to buy clothes for my business trip -did not answer phones -website went down -no apology or automatic refund, i had to call to get a manual refund

Showed up 3 hours before departure and still missed our flight. The agents were extremely slow and rude. If you have a giant line of people who have missed their flight your system obviously isn’t working. Avoid Heathrow’s British Airways by all means if possible.

Flight was very late. Reason given was a mechanical issue but last minute boarding was people whose flight out of Gatwick was cancelled and they were bussed to Heathrow so I suspect that was the real cause for the delay or at least a part of it

British Airways makes you pay for water!!! I accept paying for food and drinks but water should be free Also their machines to pay on board don’t accept USA credit cards so I couldn’t pay but a kind flight attendant allowed me to buy with card and she hand wrote info

Friendly crew once you’re on the plane.

Two flights canceled due to weather - that’s understandable. The website, app, twitter help, and phone numbers not working for info or to rebook = unacceptable. Seats in premium economy are cramped and tight.

The ground crew was very curt and non helpful. Apparently there was a rule that laptops had to be in the checked baggage. The ground crew could have been more courteous with passengers for whom this was a great inconvenience. In my specific case, the person checking me in labelled my bad "Long Stay" instead of "Priority" because they misread the instructions on the computer. The person would not listen to me and would not re-check his potential error....I fly British Airways all the time and that did not seem to make a difference in his demeanor

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.
