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.
Cons: I have flown LHR - DUB a couple of times in the last month with BA and a couple more times in the last year from LHR-DUB and not once has the flight left LHR on time and landed in DUB on time. I find this very frustrating, they appear to always be delayed by 1hr + which make it very challenging to make onward travel plans and has resulted in overnight stays at my own expense.

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.

We attempt to get accurate prices, however, prices are not guaranteed.
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.
We aggregate tons 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 don'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.
