One of the best flight experiences I've have had in along time. Would fly with them again.

So, the trip from Dublin to LA did not really happen because the flight took off before we could finish the transfer.

Very nice experience. Flight had good entertainment system and good food options. Customer service was very friendly and nice as well.

Like - the crew were nice Dislike - sitting on the tarmac for long periods after boarding and landing.

I was not admitted to the flight!!! i need a refund for this.

It’s my new favourite airline! Everything was smooth and relaxed!

One of the best flights I've been on in a while. Very genuinely friendly staff. Courteous, kind, respectful. On a past flight (not Aer Lingus) I remember being woken up rudely to put my seat forward. Like a child being berated for something. Oddly jarring experience when someone could just tap you gently on the shoulder and gesture kindly. But I noticed the Aer Lingus staff were incredibly patient with everyone on the plane. It's the holiday season and I noticed a lot more elderly customers on the plane than I typically see flying, and the staff went above and beyond with helping accommodate people. Service throughout the flight was flawless. They came through offering water, and picking up garbage at perfect intervals. Seemed like this flight, everyone was on point. And the flight landed early on top of that

Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Customer service was excellent! The app was terrible, tried several times to check in without success! But the young lady that checked us in was absolutely terrific and helpful.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.
