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!

Air Lingus was in no hurry to get us on the plane as sat at the gate a long time before they boarded us. Then they leave us on the tarmac for an hour. They were no help to let me know what I needed to do to get home. I had to navigate London Heathrow with 0 help from them.

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

This is a very basic flight with no-frills. I just wish the seats were a little bit more comfortable.

Catastrophic experience the gate selected customers were picked up to.pay 70 eur for overweight 1-2 kg. While some others were let to board without chcking their carry on bags. Unecessaey drama by Lufthansa that brings nothing just hating them by customers.

We were charged for luggage, and our ticket was with Lufthansa and was supposed to include luggage fees. So our experience was a bit bad. Also, the flight was about 45 minutes late arriving.

It was good although we could not land in Munich due to weather and we had to go to Stuttgart. Missed our second flight. They did get us on another flight but the seats where not the ones I paid for in the flight that we missed.

Smooth Flight, Friendly crew, food offering on board was limited.

The real bathroom smelled horrible and it smelled in the real of the plane..

The staff are extremely rude maybe even racist, I’ve never been treated so poorly in my life. I will never fly with Lufthansa Mor Discovery Airlines again.

Ok flight. Water and small chocolate offered. Would be good if flynet included also video.

The connection between my income flight and the outgoing flight was slightly late and they would not hold the next flight for 7 minutes. The next flight was 4 hours later and we were issued a stand by ticket. So we had to wait to find out if we would even be on that flight. After boarding that flight was delayed for 40 minutes because there wasn’t a ground crew to load the luggage. The airline is not living up to it reputation.

In this flight was no good it was delay, change of door
