Reviews of the top airlines flying from Dublin to Heathrow
No snacks, drinks or coffee. No entertainment, not comfortable seats
No snacks, drinks or coffee. No entertainment, not comfortable seats
Air Lingus was in no hurry to get us on the plane as sat at the gate a long time before they boarded us. Then they leave us on the tarmac for an hour. They were no help to let me know what I needed to do to get home. I had to navigate London Heathrow with 0 help from them.
Great. Has a problem with DOB. Fixed 4 us. Led to a 5 hour earlier flight to London!
My flights with Aer Lingus were very good and I will definitely fly with them. Again in future trips to Ireland and Scotland.
At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags
Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.
Amenity kits were never handed out. There was zero friendliness and assistance by crew. Food was uneatable. One drink was offered and no wine, with dinner or before or after. Cocktails and beverages were not encouraged and when I asked for water, none was given. Poorest, most cramped business class flight I’ve ever been on.
Short flight so not much to rate. Surprised I had to pay for a soda.
Very good need to offer better choice of food for business
Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.
I am very disappointed with the way my seat reservation was handled. My husband and I purchased Business Class tickets and also paid extra to reserve our seats. However, our reserved seats were changed without our consent, and we were assigned different seats, separating us. Since we paid specifically for reserved seats, the airline did not provide the service we purchased. I would therefore like to request a full refund of the seat reservation fees. I would appreciate your prompt response and resolution to this matter. Thank you.
We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.
Why don't they board from the back of the plane to the front. We have to move by all the people and their luggage to get to the seats.
The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?
With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.
Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer
Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.
The issue wasn’t necessarily with British Airlines but was a reaction to their delayed flight from Miami to London on Aug 18. Due to the delay out of Miami, we missed our BA flight with Aer Linguis on the 19th from London to Cork, Ireland. The attendant in London was helpful and rebooked us for a flight later that same day ($120). However, she failed to mention that as a result of the missed flight, our returning flight was also cancelled and the rebooking cost was $451. Disappointed at the lack of communication between airlines and between the agent and the customer.
Lost bag on an hour and a half flight with no connections - ridiculous!
You lost my luggage on the trip to Dublin and again on the way back, still waiting on luggage.
