Pros: When I finally settled into my seat on the British Airline and that Hostess came around and offered me a couple of free drinks that was the best thing that happened to me all day.

Cons: For an older couple like us did not like having to climb the steps up into the Plane and being out in the rain did not help. However that was not the worst part of the arrangement between getting off the Aer Lingus plane and with so little time to reach the gate for our BA flight to Denver it was a total disaster. Due to a minor problem my wife had with her foot I had asked for a wheel-chair to be available when we got off the plane at Heatrow. Good job that I did because with out their help we would never have made it in time for your flight to Denver. Between up and down in elevators, running along the corridors, in and out of a bus and I myself trying to catch up with those poor attendants. I was sorry that I did not get a second wheel chair for my self. Only for the flight was delayed by about 20 minutes we would have missed the flight. Who ever was responsible for making the arrangements of just allowing a time of 1 hour and 10 minutes between flights needs to figure out a better time schedule before people of our age ends up getting stressed out and end up with a heart attack. Very stressful indeed, believe I will never let this happen to me again. Fly/Us you need to fix this.

Pros: Going through US Customs in Dublin is great, makes The landing home so much easier.

Cons: The airline made people unnecessarily nervous by posting a very early boarding time so people thought they had to jump in line in customs when, in fact, we all had the same departure times and all had plenty of time.

Pros: the seat configuration is 2/4/2 so if you get a seat by the window, you have your significant other or friend next to you and no one else which is nice. Food was decent.

Cons: Entertainment didn't have any interesting movies or TV shows. Bottom of the barrel. No coffee or tea was offered before landing and it was advertised.

Excellent 9.3

Pros: The crew was extremely efficient in everything they did. Beverage service was super but many of us didn't know we could get our own from the front of the plane.

Cons: The seats lean too far back and are hard to get in and out of. There's very little space for anyone in the middle seats to move, much less climb out from. Oh, it was never clear to the passengers that anyone could get up and get drinks from up front during the flight.

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.
