The first flight was delayed and left us with a tight connection from Dublin to LAX. We would have made it and only had carry on luggage, however we were turned away and not allowed to go to the gate because they gave our seats away!

The first flight was delayed and left us with a tight connection from Dublin to LAX. We would have made it and only had carry on luggage, however we were turned away and not allowed to go to the gate because they gave our seats away!

I was not permitted to check in online and there was no one at the check in desk at FCO when I arrived, so I could not get to my flight. Did not receive compensation of any kind.

Boarding was messy and the flight was delayed an hour

Food was mediocre, but as expected in economy class on an airline. Wrap was ice cold , my son’s served by a steward on the next aisle was warm . As expected, but at least heat the food up a bit. No frills, but it’s economy. Excellent free WiFi was a bonus

The overall sports experience wasn’t even OK. The fact I canceled when I was on my way to get food at the airport again this was a international flight. I was out of the country and I did have work the next day. It was very inconvenience and very last minute and it was very poorly communicated.

Informed of delay the day of flight resulted in us getting to our destination hours later. Had we been notified earlier plans could have been rearranged. No airline employee could tell us why there was such a delay. Smells of trying to hide the real reason Food was not offered to us. Stewardess walked right passed us offering others drinks and food. I thought on a short flight maybe they paid for it so I didn’t ask. Turns out they should have offered us something Seats were very hard and uncomfortable

Terrible. The flight from Athens was delayed and we missed the connected flight to USA. They will put service was unacceptable, we had insufficient information, and the whole experience was awful.

My luggage was lost and still has not been found. Apparently there is a disconnect between Aer Lingus and American Airlines regarding the transfer of luggage that needs to be corrected.

I flew Aer Lingus Business class for the first time. Having flown economy a few times, I was familiar with the airline, and happy enough with economy. I’ve certainly been in nicer economy airlines before, but Aer Lingus is usually very reasonable, and I find the staff to be kind and have an Irish sense of humor and accommodation. The business experience was good, in that you got superior service to the back, lay down seats, better food and drinks, and more attentive service. However, the plane was a bit older, the WiFi was slow(not Starlink) and the pods were too close to one another for privacy, or function. When the Oder lady to the left of me fell asleep(fully reclined) there was no way for me to escape without having to wake her and put her seat all the way up. That lead to me being stuck with luggage I couldn’t put away in a cramped(for business) space, and no way to use the restroom for almost the whole 8 1/2 hour trip. I ended up trying to sleep with a large backpack blocking my feet. The food was good for plane food, but not great. The drinks were great, shame I couldn’t have had more, but I’d have peed myself. I love a window, but next time maybe an isle seat. Overall, the experience was good, not great, but an expensive good experience during which I got zero sleep. I’d do it again, but it’d have to be a deal.

The direct flight was a superb idea; please continue. The seats were less than comfortable for such a long flight.
