At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

Seats weren't very comfortable for a long haul flight but the service made up for it.

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

Noted in last review. Good to know, though air Lingus on European flights does not offer any food or drink, even though we were on the plane for 3 1/2 hours from Naples to Dublin everything you had to purchase even water.

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

There was no flight. I booked a flight from Toronto to Bordeaux with a stopover in Dublin. I arrived in Dublin and the flight number I had didn't exist and the flight going to Bordeaux I wasn't on. I had to book a new flight with a different airline for later in the day and pay out of pocket.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.
