The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

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

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

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Air Lingus flights were delayed on each of the three flights we took. Not a very good , and organized airline.

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

Would be better if there is phone charging ports available

We arrived at the airport by taxi so as to be there two hours ahead of take-off. On arrival I received a message stating that the flight would be 85 minutes later than planned. An hour later another message stated that it would be a further 20 minutes late. There was no mention of the almost 2 hour delay once we boarded. Needless to say, they didn’t trumpet their “arrive-on-time” signal. At least we got there eventually.

Long delay. Terrible airport - too busy, not enough seating or food/drink outlets.

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.

Staff member at boarding gate was rude, and more than once!

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.
