They lost my bag so that is unfortunate.. still waiting for it

Didn’t have requested food and seats could be more comfortable.

Flight attendants on this flight were very lovely. Hot food was terrible. Canned wine felt elevated and was GOOD. The aircraft was overall not very clean. Although this one was much more cleanly than the flight from Pisa. Pilots were great & landings felt smooth and safe. As I mentioned in my last review, this was my first time flying aer Lingus in many years and I cannot say I will be rushing to book again. This airline needs a real facelift.

Everything went extremely smoothly! They boarded by groupings of seat numbers starting from back to front. All staff very helpful and accommodating. Food and beverage plentiful and good.

The plane from Venice to Dublin ran out of food. They did not restock the plane in Venice.

It was very refreshing being in a nice and clean plain, with pillows and earphones that you don’t have to pay for, with warm food and beverages and a very nice crew

The flight from Dublin to London was short but they charged for any food or beverage. I have never paid for anything except alcohol on a flight before so imagine my shock at being charged nearly 4 pounds for a cup of tea. I once took an hour and a half flight (different airline) within South Africa and was served a complimentary dinner. It’s minor things like this that might make me hesitant to choose Aer Lingus over another similarly priced airline.

Ground crew in Dublin also not friendly, I had a tracker in my bag that was showing the bag was left in Canada however they didn’t want to help.

The thing thy call a pizza was atrocious. Do not eat it. The seating is as usual for economy an experiment in cruel and unusual punishment that they aren't allowed to do to prisoners but you get to pay for it.

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
