Airline reviews

My experience with Aer Lingus was not too good. First, because of the last minute delayed flight from Amsterdam to Dublin we almost missed our flight from Dublin to Philadelphia. Secondly, the flight from Dublin to Philadelphia had very uncomfortable seats especially it was a very long flight. My buttocks were constantly in pain for sitting on these seats for this long. Lastly, the service in the plane was also slow. I asked for a second cup of water and the hostess told me he'll be right back with that where it took him over an hour to come back with water. It was warm in the plane and I was very thirsty. Overall this airline needs much improvement in their services.

Staff was generally friendly and helpful. Attendants collecting trash were somewhat inattentive though.

This flight left about 45 minutes late, and arrived about 45 minutes late, which was enough to make us miss our next flight and trap us in Dublin for 24 hours!!

I think the extra charges for seating with no added advantage and the added charges for baggage are excessive compared to other airlines.

I had zero issues with the flight. I did have issues with the staff at the airport. We missed out flight due to a delay with another airline. Talking to the staff and trying to get a new flight arranged was challenging. One guy was able to try to help us and got us on a new flight, but other staff was dismissive and clearly let us know it wasn’t their problem. All I kept thinking was… this is why air lingus has such a poor customer service reputation. I will be avoiding this airline in the future.

Food was just okay. Was surprised initially when was charged for a cup of tea when they first came through cabin for beverages. I’ve had far better long distance flights ( take some tips from Swiss airlines)

The boarding process was not good. From check-in, there was only one desk for check-in, which made for a very long line. I asked to print out my boarding pass for the next leg of my trip, also via Aer Lingus, and they said they couldn't. I was unable to do this on the app or online, either. Many fellow passengers I spoke to had the same issue. Because the plane was delayed taking off by 90 minutes, everyone had to quickly go to a desk for their next boarding pass which was chaos. Overall it wasn't a smooth or happy experience.

UNDERPRISER IS A CRIMINAL ORGANIZATION. I WILL NEVER LET THEM MANAGE ANOTHER TRIP. THEY ESSENTIALLY WERE TRYING TO EXTORT ME FOR "Permission" FROM THEM not TO USE MY ROME TO DUBLIN FLIGHT. I did not use this flight, and despite many communications with both Aer Lingus and Underpricers, to the end, they insisted I could not do this, while Aer Lingus kept telling me there was no problem. And in fact, I had zero problems catching that second leg of the trip home from Dublin to LAX.. As if harrassment, underpricers sent me a rude and insensitve email insisting Aer Lingus would not honor the flight home to LAX from DUB. ON THE MORNING OF THE TRAVEL!!! KAYAK SHOULD NOT USE UNDERPRICER "services" They are dishonest and sadistic.

We left 2 1/2 hours late. It wasn't the airlines fault but they did nothing to help the situation. Even water had a price tag. The next flight was better.

They specifically asked about my flight from bordeaux to Dublin, which was fine. A little lacking but for a 1 and a half hour flight - it was more than enough. I transferred at Dublin and went to Newark. And wow that flight was incredible.

Needs faster boarding procedure. Not their fault but should still take into account indifferent flyers.

Very fast boarding. Crew members were super nice. I loved it!

My luggage got lost and until today there is no solution to the problem. It's still missing

I am writing to demand an immediate refund and compensation for the absolutely unacceptable experience I endured with VUELING this week. On Monday, my flight was canceled, and despite this, I have yet to receive any refund. I was then taken to a hotel in a terrible location, where no food or even water was provided. The next day, I was rebooked on another flight, for which I had to personally cover an additional €50 in transportation costs—only to have that flight canceled as well. After waiting 10 hours, only 10 of us were offered alternative accommodations, while the rest were left stranded. We were forced to remain in this situation until Thursday without a single explanation or proper assistance. During this entire ordeal, we were only provided with breakfast and dinner, while being charged extra for drinks. This level of treatment is completely unacceptable. I expect an immediate refund for the cancelled flights and full compensation for the inconvenience, additional expenses, and the significant distress caused.

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

Nothing. There was no flight. They cancelled the flight with no replacement about 9 hours before takeoff.

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

Boarding with some sense and communication. It was a total free-for-all everyone coming all at once, no organisation of row numbers or priority.

Horrible, flight cancelled and had to come back the next day
