The exit row has amazing leg room, but you can’t use your tv screen like other passengers (can’t listen to movies because there is no aux plug and no usb to charge your phone like other passengers)

A person should not have to physically run and have stress of wait to get thru TSA then run again back,get on train to next plane.Other passengers then said "ou are why we are starting late". It was a transfer off a plane from Ireland not a traffic issue. BA SHOULD HAVE PUT ME ON A LATER FLIGHT. TO SEATTLE.

Cons: Flight was delayed once we had boarded, so we had to sit at the gate for about 2 hours, which was not the crew's fault of course, however, they could have offered drinks. Once we finally got in the air, they only offered purchasable snacks in a way that was confusing--and did not even come through the cabin with complimentary drinks. Given the circumstances, and the fact the time in our seats was extended by over two hours, there could have been some better service from the actual flight attendants. It should have been clearly stated at the beginning of the flight, and once more when we were in the air, that no complimentary drinks were going to be handed out, and if we wanted anything, we would need to purchase it. I wouldn't have minded purchasing if I had known that was my only option.

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.
