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

I believe it was short flight in plane I understand not that much compared to other airlines but weighting for checkin was too long need extra person for checkin or Atleast someone to let the customer knows don’t worry someone will be here shortly.

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.

Seats were alarming close to the row in front of you. I didn’t do the measurements online, which I’m sure they’re available, but it seemed much tighter than other planes, but the airplane itself was well maintained and looked fairly new. My only complaint on the staff was that we’re on an international flight. Normally they give you wine with dinner and the flight attendant decided to pull some strict restrictions and wouldn’t give more than one glass of wine per person, and you could not share with your spouse, which seemed ridiculous when we have four people on the plane with us and only one person ordered wine asked for a second one and she said oh absolutely not. It’s only one per person Which on a transcontinental usually is not the case. They’re very attentive on making sure everyone is as comfortable as possible.

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

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

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.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!
