Pros: All staff were very helpful and polite

Cons: This flight was delayed. When it came to boarding my husband who needs special assistance was first taken to board first but then had to be brought back as refuelling was not done and was then last on board. When we arrived at Heathrow his special assistance was not there and we had to wait for about 10/15 minutes. It is stressful traveling with someone who needs help and even worse when there are delays. We were advised that we could leave the aircraft which we did but we were left waiting in an area without any toilets which is a problem for him

Pros: Service manager Alan and crew were lovely, very friendly and felt genuinely happy to help us. I have never been given so much free stuff on a plane before! The snacks and beverage offerings just kept coming. I enjoyed my warm meal. Entertainment offerings were good, and as we were on a newer plane the technology was better than other flights I’ve been on.

Cons: Seats could have been a bit more comfortable and roomy, but they were decent and I didn’t have too much trouble sleeping.

Pros: The snack provided onboard was tasty. The flight attendants took their job seriously.

Cons: Southwest Airlines style seating with a foldable tray table over a middle seat. Sold as a business class cabin at a high price for an hour and a half flight but we left feeling ripped off. No boarding order and overall chaos boarding. I feel that for the price and being advertised as business class I was taken for a ride so to speak, and not in a good way. This would not qualify as business class on any other airline irregardless of how short the leg was.

Cons: Truly disappointed to find that BA has decided to charge for ANY beverage whatsoever, even tea. I have such fond memories of flying BA years ago. My husband and I so enjoyed the disposable plastic blue teacups that we brought them home with us and still use them as kitchen scoops all these years later. I know that may seem silly, but even without that nostalgic memory, it just feels SUPER unpleasant to have to pay for the basic (non-alcoholic) beverage service. Honestly, just charge a few bucks extra on the ticket in the first place.

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

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 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.

If you have more questions or if you have a bad price to report to us,
