Pros: Comfortable seats and did not have to pay extra for a carryon luggage

Cons: The boarding process was quite chaotic and slow. There was no oversight of what people were putting in the overhead compartment so many were putting both their carryon suitcase and under seat bags up there leaving no room for our suitcases by the time we boarded. The flight attendants were eventually helpful in finding space by making people remove smaller items, but it was time consuming and avoided on most airlines we typically fly by enforcing bag rules as passengers are boarding.

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.

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.
