There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

They lost my baggage on my connecting flight and we’re an hour late so I nearly missed it

Thankfully not a full flight so although my headphone jack wasn’t working 100% on my window seat, I was able to move to the aisle seat. Food was fine, nothing great but tasty enough. Crew were friendly and made enough rounds. Always have a decent experience with Aer Lingus

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Staff are so nice and friendly, plane was very clean and plenty of leg room

It was cold the whole flight. Luckily had Ski-Jacket with hoodie. The food was just boiled macaroni in 'ketchup'. Better bring your own BigMac. Assisted Boarding was SUPERB!

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

This was a late night flight but the lights was on all the time and kids were screaming and many people were so loud. I was expecting to have a little rest on the plane considering it is late night but this way I couldn't. I think if at least the light would've been off / lower then people could feel they should be quieter.

Everything was great - but then had to wait one hour for my luggage in Verona…

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

I didn’t get to London or Amsterdam. They lost my connection flight . I was stuck in Madrid and they rerouted my flight to Austria where my son had to come and pick me up. To get to my destination and they lost my luggage and they’ve told me they can not find it very poor service so have no word for what happened

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

Overall good, but the fact that there was no WiFi was a big deal for me. I am not used to having no WiFi during long flights. I always fly Delta-KLM and they never have had an issue with WiFi.

I asked for a wheelchair. I have a back health condition. I had to walk a lot

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Boarding = No one respected the boarding groups. The ground crew did nothing to enforce the boarding system. What is the point of being a Gold member when there are no benefits to that? Tired old plane
