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.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

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.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

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

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Golf Bags never made it on the flight. Very expensive golf bag and. Clubs,shoes, clothing. Will file a claim against Aer Lingus

Horrible. Garbage airline. Due to the strike we got a replacement plane/crew. I didn't get my exit row seat I paid for. Food was horrible. Plane was hot and didn't have AC vents.

The first leg of my 2 flights were delayed, causing me to miss my second flight and have to stay the whole night in Dublin. Super upset with this experience, and I still need to figure out how to get compensated for this.
