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.

Didn't make it to this flight as we sat on the tarmac for 1.5 hours.

flight delay was announced after passengers were staged to board the flight. Communication regarding subsequent gate changes was poor.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Just pushing back from gate now. Boarded into fourth aircraft with 13 hour delay to scheduled departure. Crappy experience.

Notified as to why there’s a delay with our flight.

From boarding to disembarking, the whole operation was very efficient.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Flight got delayed and they didn’t keep us informed all the time.

Blood contaminated tissue was stuffed to the back of the seat in front of us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

How about changing the personal out to more friendly human beings? This team was pretty arrogant. No fun!!

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Lufthansa staff was fantastic, but the airport was a mess. I was at this airport in the past and I have never experienced any problem, but this time it was nutty because of soccer tournament: UEFA 2024 championship

What food? What entertainment? The questionnaire does not make sense.

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.

Staff and crew were very helpful. I wish there was less delays on the flights that made it stressful for the connecting flights.

The transatlantic leg was on Discover Airlines. I’m 6’2” and the extra leg room seat was acceptable, the seat it self was moderately comfortable (slightly softer than a church pew). The food was a standard economy fare. Frankfurt to Prague leg was on Lufthansa the business class was as advertised 10 across the board.

It was only an hour flight, but at that, it was still late
