Pros: Overall it was fine. Friendly staff, everything pretty efficient.

Cons: Truly disappointed to find that BA has decided to charge for ANY beverage whatsoever, even tea. I have such fond memories of flying BA years ago. My husband and I so enjoyed the disposable plastic blue teacups that we brought them home with us and still use them as kitchen scoops all these years later. I know that may seem silly, but even without that nostalgic memory, it just feels SUPER unpleasant to have to pay for the basic (non-alcoholic) beverage service. Honestly, just charge a few bucks extra on the ticket in the first place.

Pros: The snack provided onboard was tasty. The flight attendants took their job seriously.

Cons: Southwest Airlines style seating with a foldable tray table over a middle seat. Sold as a business class cabin at a high price for an hour and a half flight but we left feeling ripped off. No boarding order and overall chaos boarding. I feel that for the price and being advertised as business class I was taken for a ride so to speak, and not in a good way. This would not qualify as business class on any other airline irregardless of how short the leg was.

DUB

OK 5.0

Pros: Replacement flight was fine

Cons: Flight was cancelled and I was not automatically re-booked, luggage lost and not delivered despite repeated effort to reclaim it. Aer Lingus hold time on the phone was over an hour and attendants were unhelpful (said my flight wasn't cancelled in their system even though I received an email that it was - which ended up being true)

DUB
LHR
OK 4.0

Pros: British Airways certainly has slipped. Very mediocre service.

Cons: Didn't tell us if/when we would be eating. I called for a flat attendant twice, with no response. When I pointed this out, she said that she knew they would be coming through the cabin with drinks, so she didn't bother to respond. Just so long as it was easy for her...

DUB
LHR
OK 4.3

Pros: All staff were very helpful and polite

Cons: This flight was delayed. When it came to boarding my husband who needs special assistance was first taken to board first but then had to be brought back as refuelling was not done and was then last on board. When we arrived at Heathrow his special assistance was not there and we had to wait for about 10/15 minutes. It is stressful traveling with someone who needs help and even worse when there are delays. We were advised that we could leave the aircraft which we did but we were left waiting in an area without any toilets which is a problem for him

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".

Pros: swift boarding allowed for an earlier departure and arrival 30min ahead of scheduled time

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.

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.
