Okay 5.0

Pros: I made it

Cons: If I were a bit older or slower I wouldn’t have made plane. It is unfortunate I had two leg journey to Ireland. BWI - Heathrow- Dublin is a difficult journey with 1 hour layover. I nearly had to push old ladies out of the way to make connection. Very stressful and left headphones in haste to make flight. Not an enjoyable experience.

Mediocre 3.3

Cons: Boarding was a bit confusing and staff wasn't actively being helpful with information. Got absolutely nothing to drink/eat on the plane-not even a glass of water! The flight crew was just ok, no one "stood out" as good or excellent. Again, nothing about this flight made me want to definitely fly British Airways again.

Okay 4.0

Cons: It would be nice if someone cared about something. It didn't seem like anyone liked their job or cared about the passengers. All seemed like corporate greed. I have flown over 40,000 miles this year. This was the most unsatisfactory flight. Come on guys, create a good environment for a win win situation. Happy passengers make more money for the corporation in the end.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

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 rentals 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.
