In flight entertainment was very good. Flight attendants helpful. Seats hard but we had ample leg room on this flight. I would like to commend the pilot for landing us safely in some extremely windy conditions. Everyone on the plane was audiably nervous and he did well

Checking in was not pleasant they seated me in row 20 something and my wife in row 40 something even though the plane was half empty. Distressing at first. When I asked why they told me to sort my seating out in the plane. Now that's telling. Whoever checked me in could see there were lots off empty seats and couldn't take the time to seat my wife and I together. Hmmm. Terminal at Dublin was small and over crowded. There was 1 agent at the gate checking in everyone on this flight for about 10 minutes until she finally got some help. You must do better

Despite the delayed flight air Lingus gave us compensation bonus for a small meal and drink at the Barcelona airport after 2 hours caused by a thunderstorm.

Inflight Barcelona to Dublin air lingus were charging for drinks ( non alcoholic) and food . Which seems to me after waiting 02 hours at the airport they were suppose to compensate the customers.

Boarding was disorganized. There was no reason or logic as to how people board the plane. People sitting at the back of the plane boarded with people sitting at the front of the plane. No in flight entertainment. Seating was tight. When we landed in Dublin we were ushered onto a bus to our connecting flight. I wish they had mentioned that would happen.

Flight being changed three times and delayed multiple times. Not weather related. To top it off, the airline decides to leave my bag in the states because the flight was changed and I didn’t notify them; which of course is ignorant because they changed the flight and didn’t even notify me.

Gate agent refused to let me carry on a suitcase that I have carried on dozens of flights (this specific suitcase) and I understand overhead limitations (I have more than 4 million air miles just between United and American Airlines). This was an A320 and I was about #10 getting on the flight. Space was not an issue. This added an hour to a 25 hour day to wait for luggage at LAX. And BA gives the agents an edge in that their test fixture has rounded corners to that a 22 inch suitcase that has hard square edges at the bottom (or wheels that make it square) won't fit in it. So the agent just points that it doesn't fit and you have to check. I was not happy from Paris to London.

Plane was new and very comfortable. Smooth flight

Flight attendants had to serve food/drinks, which they did the entire flight (literally, drink service took 2 hours). People got drunk and super loud. We were late leaving London which isn’t an issue except the people at the BA desk were the least helpful. We found out more from the pilots than anyone in the airport.

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.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days.
