There was no room in the seats, smallest room we've ever had and the food was awful.

I dont fly them much anymore. Other carries offere better pricing and better seating options

Seats weren't very comfortable for a long haul flight but the service made up for it.

This flight was of exactly the same high standard as the outbound leg, exactly a week earlier - except that we didn't have any food or drink because it departed at around midnight.

The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again

I liked how they looked after couples by providing a row of 4 seats if available.

Food was very bad. Boarding was disorganized and messy. Crew was friendly

I believe it was short flight in plane I understand not that much compared to other airlines but weighting for checkin was too long need extra person for checkin or Atleast someone to let the customer knows don’t worry someone will be here shortly.

Seats were alarming close to the row in front of you. I didn’t do the measurements online, which I’m sure they’re available, but it seemed much tighter than other planes, but the airplane itself was well maintained and looked fairly new. My only complaint on the staff was that we’re on an international flight. Normally they give you wine with dinner and the flight attendant decided to pull some strict restrictions and wouldn’t give more than one glass of wine per person, and you could not share with your spouse, which seemed ridiculous when we have four people on the plane with us and only one person ordered wine asked for a second one and she said oh absolutely not. It’s only one per person Which on a transcontinental usually is not the case. They’re very attentive on making sure everyone is as comfortable as possible.

Boarding seemed a bit chaotic and we had to walk outside across the tarmac. Passengers of all ages had to drag carry on luggage up the outside stairway into the aircraft. There was no WiFi. Very uncomfortable crammed seats. Glad in-air time was only an hour!
