Airline reviews

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.

A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.

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

We had a long delay leaving IOM. No food or drunk service as it is a short flight. Shuttled by bus from terminal to plane with packed in conditions on bus.

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!

Not satisfying due to loss Luguage for 4days. Damage Luguage that had no way to fill up a report for and me as a client to spend more money and time to replace it. Thank you for soliciting my opinion, but it was unfortunately a very disappointing experience. Stephanie Zvi

Everything went well. I made my connection which is always a concern.

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.)

When I booked the flight, I wasn't aware that this was a "no frills" flight. No wifi, no reclining seat, no complimentary soft drinks.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.
