It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

The space between seats was reduced even further. Could not even open the tray table fully and got compressed the moment the front guy reclined. For a long haul flight it was extremely uncomfortable.

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.

Not satisfying due to loss Luguage for 4days. Damage Luguage that had no way to fill up a report for and me as a client to spend more money and time to replace it. Thank you for soliciting my opinion, but it was unfortunately a very disappointing experience. Stephanie Zvi

The seat pitch was a little tight for me, but I survived. There was a volatile, enraged passenger a couple of rows ahead of me and the cabin crew defused and resolved the situation calmly, quickly, and successfully.

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

I had an awful experience at the ticketing agent stand. I had purchased three tickets, one of which I had the maiden name of a passenger on the ticket. They refused to help, assist, and actually delayed our process and had us miss an opportunity to purchase a ticket on the same flight. I was sent through multiple phone calls, none of which helped, and the person at the counter was the person who told me to both call Aer Lingus for help and was the person who said they could not fulfill my request that they were privy to from the beginning. My partner is still stuck in Scotland, racking up thousands of dollars in additional fees and tickets. I am very upset and two of my tickets went unused. I will never be using Aer Lingus ever again and I will continue to complain about them.

This was the most expensive economy flight per minute of flight time ever. But the quality was lacking. Extremely Aer Lingus rude staff at LHR said that the flight from London to Dublin (Ireland) was “NOT international.” Horrified at the colonial and imperial perspective. Seats were dirty with trash in seat pockets. Airline doesn’t clean or care about hygiene and safety.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.
