Pleasant crew and good food/snack service almost forgotten as I stood at the baggage carousel for 40 minutes.

Baggage claim very frustrating (40 minutes) particularly after 12 hours of airports and airplanes. Messed up our ground transportation plans for no apparent reason. Totally unexplained!

Having had bad experiences with Aer Lingus before, I was hesitant to book with Aer Lingus again. But sadly, I was booking this flight last minute and had no other option. The route was Dublin to Calgary, via Toronto. I left myself plenty of time im Toronto to clear customs as I know it can take a while. The day of, the flight ended up being 1.5 hours longer than usual due to headwinds, leaving me with only 2.5 hours in Toronto. I ended up waiting 2 hours and 15 minutes for my bag and missing my connecting flight (my sister who was also on the same flight received hers in 30 mins and made the flight). Westjet was wonderful and put me on a later flight but Aer Lingus didn't have any assistance for me.

Aer Lingus lost my sister's luggage going to Ireland and never contacted my sister once the luggage was found. She only received it the day we flew back to Calgary. Poor customer service when inquiring about the bag, no compensation for necessities purchased.

The plane was just fantastic: comfortable, elegant, quiet. Gets the best note!

A free coffee - which was excellent by the way - and a little roll would have been nice.

I flew overnight from Toronto, Canada to Dublin and had a relatively pleasant experience. The food and drink trolleys came by quite quickly and frequently, and the food exceeded my expectations. The crew was friendly, for the most part. Boarding certainly could've been smoother... But overall, I'd fly Aer Lingus again for an overseas trip.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
