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.

There was a 6h delay with limited updates . When we got to Manchester the bus took ages to get to arrivals and we missed our train, dinner reservation. Basically lost a whole day due to arrivals Lingus!!

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.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

As four hour wait with no explanation as to why the delay Very unacceptable
