We missed that flight, and I am hoping that we will got the refund. It was very confusing to figure out about Aer Lingus operated by American Airlines. Then we bought another more expensive ticket to travel.

We missed that flight, and I am hoping that we will got the refund. It was very confusing to figure out about Aer Lingus operated by American Airlines. Then we bought another more expensive ticket to travel.

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

There was a 6h delay with limited updates . When we got to Manchester the bus took ages to get to arrivals and we missed our train, dinner reservation. Basically lost a whole day due to arrivals Lingus!!

I was pleasantly surprised and enjoyed the services of the airline since flying is not my favorite thing. My goal was to be with my brother's family in Manchester after his death. All staff was helpful, the food appreciated since I selected an overnight flight. Every aspect of the experience was comforting. I plan to return to Manchester in order to attend my brother's funeral in October and hope that I am able to find a reasonable priced flight. Thank you

Very good except for the boarding process which was more hectic than it should have been

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

Flight was excellent, staff was great. My first time in first class and it was very relaxing and comfortable.

They are disorganized….show your flight info half an hour before take off, so you are running all over the place. Customer personnel are not helpful, and act like you are bothering them when you asked for assistance - very rude!!! My very first and last time flying with British airways… good thing we have other options.

There was no entertainment offered or expected, so please disregard my readings of that component. The flight was fantastic. Efficient boarding, takeoff, and even early arrival!

2 hour delay with very little information given. Horrible service by BA employees at Heathrow after we missed our connecting flight. Extremely disappointing experience!
