I'm 6 ft 2. Legspace was adequate, and no silly boxes under the seats like other airlines that obstruct your feet. Great entertainment systems - modern, good selection. Food and staff excellent.

Their online checkin systems could operate a bit more smoothly. At one point, I had to go in in person, because the online checkin site had an already past flight from their codeshare partner SAS showing up as the next flight, and I couldn't perform online checkin as a result.

WTF is going on w an airline that would let a passenger behave like this ? Didn’t see the attendants offering a cough drop, or asking if he would please behave like a civilized human being.

Late BA flight made sure I had to wait 7 hours to catch and EVA air flight. I want my money back. I paid 1000 to flight British Airways not to be crammed on a flight as a show away. Super uncomfortable seat on EVA and a terrible experience. I fell on the plane.

I feel like the overall product is so devalued at BA these days. It just doesn't feel classy anymore. As opposed to Lufthansa, which is an example of a European carrier that cares about passenger comfort and experience. Also the typical circling of LHR to get a slot is annoying and makes me want to avoid BA.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

between lunch and supper snack one isle had only one water serving and my isle had none. So for 6 hours we had no water serving. This is why I gave crew rating OK only.

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,
