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.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

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.

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.

Worst: long walk to baggage claim Best: left on time

Got in on time. Food was the worst ever. Comfort was terrible. Check in was incredibly bad.

The flight schedules are better than some airlines. Their website is terrible, it doesn’t store any information so every time you fly you have to re-enter the data. The flight was late taking off but we still got to our destination on time.

Flight delayed by >1 hour. Long boarding involving riding a shuttle to the plane.

When I tried to enter my identity details, your app told me information was missing but did not highlight the missing data. This was frustrating. Also, there was an unexplained delay of about 2 hours in taking off. This was also frustrating. Otherwise the experience was good.

The flight was delayed without any type of notice. After passing through the gate, people were lined up at the passages boarding bridge standing for about half hour with no clue when they can board after ‘boarding’. No explanation or indication of the new departure time. All you can do is standing up and waiting.

First, I was moved from my scheduled flight at 10:45 to 6:30. Bad form as I had a scheduled lesson in the morning that I couldn't get a refund for. Second, we were bused out to the plane and bused back to the terminal and sat and sat all with NO explanation until the end of the long wait. Third, once we boarded the plane, we again sat for at least an hour WITH NO EXPLANATORY ANNOUNCEMENT. Plane left and arrived 2 hours late. I missed a train connection adding hours to my trip home. Lastly, it's time the airport is upgraded or TAP gets priority for walk-on gates. As a 74 year old, carrying my carry on luggage up and down stairs between the terminal and the plane is a pain. Might be the last time I fly TAP.
