I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

Overall good. We weren't able to find out about food options for the flight and there was nothing I could eat due to allergies. The biggest problem was getting our checked bag at Logan. Waited an hour!

I loved both of my flights to Ireland and back to Boston. The only negative was it took over an hour for the baggage to be delivered.

The boarding time for this flight was ridiculous, longest in all my time flying. There was a problem with the original plane so it was switched at the last minute. Not a good substitution. We were delayed in departing. The bathrooms for economy were not adequate. The crew were pleasant but not present in the economy section, in an ~ 8hr flight only twice did they come through offering water, easy to get very dehydrated. I had to go and ask every hour for more water. The seats were cramped, and I have no idea what they did to the coffee but it was undrinkable. The food, was disgusting, utterly inedible, I am stunned by the lack of care and quality with the inflight service, very disappointing, I had expected better from Aer Lingus.

Excellent cabin crew. They helped a number of passengers with mobility challenges and a mother with a 3 year old and an infant. Better than most other airlines by far. Well done Eduardo!

Good, I slept the entire flight so I cannot add many inflight details

Internet didn’t work more than 30 seconds at a time. Stared at my seat for most of the flight.

We had a connection flight in Toronto and the checked bags didn’t arrive to the baggage claim area 1.5 hours later- this caused us to miss our flight because of the delay. I called Aer Lingus to see if they could help, but since I booked it through a third party on Kayak, they said they couldn’t help. Are you able to help with this? We needed up getting a hotel and renting a car for the solution.

I didn't know if the plane was even go And the plane shook like it was from the same era as Indiana Jones

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg
