Everything went okay for us on this flight. In the future, I will suggest to my wife, who books air travel for us to read the fine print. The cost to check a bag was $100.00 which would have run us $300.00 for the trip: Boston to Brussels with a layover in Reykjavik, but on the return Brussels to Reykjavik with four days in Iceland and the return to Boston, so there goes the cheap flight! I did enjoy the in-flight movie and a documentary on the return trip as well.

My own earphones on the flight from Brussels to Iceland did not work. I could not plug them into the system.

They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

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.

Great legroom, nice crew.

The confusion about whether or not our flight was going to be on time was extremely stressful. Our first flight got delayed 90 minutes and our second flight got moved up 30 minutes, so our two hour delay shrunk to 0 minutes. The flight crew in Paris had no information about whether or not they were going to hold our flight, and we all sprinted through the airport in Iceland to board our second flight.

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,
