All aspects were excellent - it helped that the flight was only 2/3 full and I had no one sitting in my row. The Pre-check (US Passport Control and Customs) in Dublin made everything so easy when we arrived in Chicago.

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

Great. Has a problem with DOB. Fixed 4 us. Led to a 5 hour earlier flight to London!

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

Old plane, sold out on snacks, just trashy seats..broken..etc

Good flight. Only negative was the bus journey from plane to the terminal. Didn’t exit t this either BA at T5

Nothing! They canceled our flight to Greece the morning we were supposed to leave and offered us another one 5 days later (for a 9 day trip). They said it was an “operational decision”! Yeah a 777 that was 2/3rds empty, so they probably sent it to the Middle East to make a fortune getting people out of there!!

WiFi wasn’t available to economy until the end of the flight.

Boarding crew were extremely rude. At check in, I showed a medical note from a surgeon stating that I had a medical problem that caused me to end up in an emergency room. The surgeon requested that I get an upgrade so I can travel back home comfortably since I was in a lot of pain. I was alone with my daughters (9 and 14). They made a huge deal about giving me seats although there were so many empty seats in business. Finally, I paid a hefty price for it and the seats were exactly the same as in economy cabins but not as good because there was a forced tray in the middle seat that I couldnt even lift so I can lay down.

Very good staff members with sincere passion and responsibility in their job.

We were unable to check in on line with no explanation! Despite arriving at the airport 3 hours before deprture, my wife and I had no allocated seats and ended up being seated seperately. This is unacceptable! We were both ib the middle of the centre of the aircraft, despite having previously requested an aisle and seat next to it when booking and having been an Exec Club member for 25 years - so much for loyalty! The seats were extremely uncomfortable for such a long flight. I fly a lot and these were, by far, the most uncomfortable seats I've had in many years. It was all fine until we arrived at LHR where we got off the plane quickly, but then had to wait more than 45 minutes in the baggage hall for our bags to arrive, despite the fact that some luggage was already off when we got to the carousel. After 14 1/2 hours flying, this is completely unacceptable and ruined the experience for us.

Very please with the seating that the Kayak staff booked for us!

I liked the movie selection and the speed getting the luggage. I did not like the fact that for premium they did not have a personal kit with toothpaste, I travel all the time in premium economy and bussiness and althought the kit might bot be the same at least you have the smalles kit in premium economy. I did not like either that because i was in the last row of premium economy nothing made it to my seat. They run out of the food I wanted ( it is a surprise because there were only 6-7 rows. They would run out of orange jouice were thy were passing water/orange juice around, they run out of some alcohol. I am undertand running out of it but I don’t understand why mot getting kore. The service I received in row 11 was different from the service in rows 7,8…. Also the screen on my tv was broken. It did not respond to touch. So, in conclusion, if I compare my flight going to Europe with an American airline plane in premium and the one with British, British expereince was significantly much worse. This company is declining fast.

The crew on the flight were not particularly pleasant and fluid restriction was an issue. I was not allowed to fill my water bottle. Crew didn't check on passengers other than meal service.
