Cons: Club World is a super dated product. The tech is old and you are uncomfortably close to your neighbors. Also even when you buy a business class ticket British Airways makes you pay to reserve a seat in advance if you don’t have status with them. That feels over the top for a premium customer.

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.

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
Please send us an and someone from our team will get back to you promptly.
