Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

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.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

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!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Was not aware that Aer Lingus was like the cut-rate services in the states, with no food or beverage (other then 3.50 Euro coffee) and no screens for entertainment. Was a great flight, but not much in the way of services.

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

Flight was fine, 1st plane was a bit old entertainment, 2nd the display was freezing/ crashing every 30min. We had problems getting at gate and waited 2hr to get a gate in Toronto, then had a 90min mechanical delay at the next departure. Weather was bad and I’m just happy we didn’t get stuck.

Very nice Crew! Not much entertainment, but it was only a short flight, so it is okay for this flight.

I liked nothing about this flight nor the incredible lack of service and communication on this flight from the Captain to every staff member. Arrogant, entitled and lacking any kind of basic customer service

Everything should be better, terrible flight and airport service. Delayed for 6 hours, flying around for 1 hr, and keeping us on a plane for another 2,5 -3hrs.

I liked not paying for carry on and the compensation my husband and I received from the airline for overbooking our flight. The staff was very friendly and helpful.

My flight from Mexico City to Boston would have been fine, had I taken it, but because the final leg of the trip from Toronto to Boston was cancelled, I decided to fly on another carrier out of Mexico City that offered me a non, stop-direct route. Prior to this, I received several emails and text messages from Air Canada in regards to their Toronto to Boston flight being cancelled and about a similiar flights that departed much later that evening or the following day from Toronto to Boston. I would have hoped that Air Canada would have offered to seat on AeroMexico, but they did not. I flew on AeroMexico from Mexico City to Boston (direct) and enjoyed a wonderful flight. I replied to texts Air Canada's about my situation, but got no response. I have asked to be considered for a partial refund from Air Canada for the missed portion of my flight that I took with AeroMexico. I have yet to hear back.

Once we finally go under way it was excellent. But I hate that they changed the plane therefor the seat configuration.

I booked my flight ni November and was placed on standby? How does this happen. Flight was 1 1/2 hours late departure plane was switched to a smaller plane easy to tell this is a government run company they don’t care about anyone
