Crew, entertainment and food service was excellent

Seats too crowded for 8 hour flight. As soon as the person in front leans back you have no room it is unbelievably uncomfortable to have a seat back in your face for that long!

It was a pleasant enough trip. Friendly crew, surprisingly decent food for a flight, and some decent entertainment available, though admittedly my headphones broke within a couple of hours for some reason, but by then I was nearly asleep anyway.

It wasn't very comfortable and I had basically no leg room, but then, I sat in economy, so I can't be too surprised by that. Otherwise it was a good flight.

The flight attendents were fabulous, very friendly and helpful. I sat in the first row and when I boarded the attendant helped me find a spot for my carry on luggage.

I paid for priority boarding but never had the chance to board early.

Passengers line up to board instead of waiting for their number rows to be called. I ended up boarding later than most and the overhead lockers of the front rows (where I was sitting) were completely full. I had to place my baggage very far back and wait for almost everyone to leave the plane so I could collect it.

Crew was attentive and efficient. The flight was smooth aside from the minor turbulence.

I sat in a seat with a broken entertainment screen and the WiFi was so slow it was unusable. The seat I sat in also would recline on its own at times. It made for a very long annoying and boring flight.

Basically ontime although a bit delayed getting started. Crew was attentive . Food Ok. Seating could be a bit better.

Somewhat tight seating. More reclining of seat would help. The gate was the furthest away possible requiring a very long walk.

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

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

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,
