Cons: The purchase through a third party vendor on Kayak was a disaster. disclosure was not given about class of service purchased and limitations of that class of service. I spent so much on luggage costs and change fees I could have purchased first class. I will never book through Kayak again - will always go straight to the airline for purchase. This was a disaster.

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: Good to have movies to pass time on lng flight.

Cons: 2 days prior to returnflight I called stating the at was not enough time to catch a flight transfer having to go thru tsa again . B A assurred me I was o.k. ..It was not. 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.

Pros: The seats were much more comfortable then my last flight. The entertainment system was also updated from the 1980’s remote and cord ones on my flight from DC to Paris.

Cons: There was no food between the two meals on an 8 hour flight. I had a flight attendant rudely tell me that there is nothing to offer until the next meal. No one reached out to me about the horrible flight and comments I made from the last flight.

Good 7.0

Pros: Good aircraft, good service, on time, eventless

Cons: There are two types of foot-rests, both are a nuisance for people with long legs. The one popping up from below one's seat is extremely hard to put back in place. The metallic one folding down from under the seat in front cannot be secured back and is always in the way if the passenger needs to stretch his/her legs. This seems to be a new appliance, and I jut wish they would do away with it altogether. More is not necessarily better.

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