Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

Terrible. The test of an airline is how they deal with problems. There is very little to differentiate between airlines. Aer Lingus failed absolutely. They lost one of my bags even though we had more than a 2 hour connection in Dublin. Trying to get it back has been awful. In checking on line I can see that the bag is in Edinburgh and it was supposed to be delivered today. It wasn't. The number we have in the UK doesn't answer. I had to pay for an international call to speak to somebody. All the woman at the call centre could say was be patient wait. I can tell you when it will be delivered nor can I tell you who the courier is.

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.

Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.

I was very disappointed that the online sys allowed me to get the boarding pass for the second leg of the trip, when I clearly request it for both flights!

My experience with Aer Lingus was nice, and I would be happy to fly with them again. However, my seat pocket had not been cleaned and had dirty wipes in it. I have flown with Aer Lingus before and do not recall anything like that happening, so presumably this was a one-off kind of thing. For the meal, I asked if there was possibly one without my allergens and the flight attendant gave me the one she thought would be fine. She did not know what allergens were in it, but when I received the meal the allergens were all listed right on the top of the package, so I was confused about why she didn’t know how to check what they were. In future, I will see if it’s possible to request an allergen-free meal ahead of time. But overall, I had a pleasant experience. My experience with Underpricer was very unenjoyable and because of them I do not plan to book through Kayak in the future. I have used Kayak numerous times, but this booking experience was so unpleasant. They called me numerous times and also emailed me to try to get me to select a seat. However, when I had a question later on, I was kept on hold for 20/30 minutes before I finally hung up. I also emailed them but never received a response, which I did not appreciate, especially given their previous frequent calls when they wanted something from me.

I appteciate the very courteous staff. The flight was good. Something that wasn't good was that my bag was only checked as far as Dublin and I had a connecting flight to Vienna. (That was a mistake the ORD desk made.) Fortunately the desk at DUB was able to re-tag without me having to re-check in (which initially it seemed I might have to do.)

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

Charging for coffee on a business class fare??? And to not even mention it? Inexcusable. Boarding and disembarking was pathetic. Could not use a jetway on either end. Had to use stairs and walk across tarmac at origination and use stairs and be bussed to terminal at destination.

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.
