On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

Most narrow seat of my life. Easyjet has larger seats. And as I just wrote in the last comment section - Seat 1A promises luxury after a great businessflight. Instead, it's narrow, the seatbelt is 20cm shorter than the one in 1B, it's just a joke.

No snacks, drinks or coffee. No entertainment, not comfortable seats

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

A special shout-out to one of the check-in staff at DUB yesterday noon. We had to use the "Closing Flights" counter and we met, hands down, the most efficient person - able to resolve several issues in the matter of minutes, while remaining polite and calming everyone down. Great job, Aer Lingus!

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

Almost as usual, half an hour take off dilay, on the other hand - the checked in baggage arrived as magic super quickly. By the way - why do you ask to rate the food and entertainment on flights without them? at least offer the option of "Not Relevant" or similar...

Comfy seats, great cabin service and a very relaxed experience

To complex. So many types of fare. This made the boarding a caos.

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.

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.

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

No complimentary snacks, but I think that’s a standard in the USA. There were loud drunk Germans sitting in front of us.

I will never fly vueling. 1h30 delayed, connexion missed with the crew closing the boarding in front of us. 40 people missed the Barcelona-Orly connexion. hours waiting for rebooking and hotel.. inadmissible

Last time bucking this company if I would know I wouldn’t do it, they made me lose my flight

Awful, the plane was on time but Ryan Air chose to use it for another flight that was running late to avoid the 3 hour penalty so our own flight was 1.5 hours late. This meant a 1 am scheduled landing became 2..30 and we missed our car hire which costs us an extra £300 to rebook - bloody shambles

The airline gets you from one place to another in a reasonable time. Not much more you can expect.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.

I liked nothing. An extremely uncomfortable flight, staff were rude, no ice for my drink. 4 hours of misery

The check-in process is very confusing. The company charges for everything, but tickets are low priced. I probably wouldn't take the airline for a flight over 3 hours. The seats are uncomfortable. There's no net on the seats to hold things like headphones, a folder or anything.

Flight delayed. Sat for more than 30 min with no air conditioning on a very hot day.

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

Boarding was chaotic, the gate changed 4 times and we took off 1 hour late

Bag check in was terrible. Arrived 2 hours and 10 minutes ahead of required time and then waited 50 minutes in line to check ONE bag. There were 4 employees standing around as only two were checking bags and there were 6 gates available to check bags. Process is terrible. Lack of customer concern and service.
