The staff were fine, nothing really great, but nothing bad either.

So, we'll start with boarding. Why airlines can't figure out to board the plane from back to front is beyond me. No, let's load front to back so everyone has to uncomfortably shove past the people who have already taken their seats at the front of the plane. Then you get back there and all the overhead bins are full because everyone takes as many bags as possible onto the plane. Then you have to sacrifice the already tiny amount of foot room, "to put the bag fully underneath the seat in front of you." At this point you should be fine, except if you're over five and a half feet tall (I don't know if that's true I'm 6'2" and 275 lbs,) because then your knees are going to be buried so deep in the chair in front of you that the person up there doesn't even need a seat they can just sit on your knees. Luckily for you tall people, they put a nice metal rod just about knee level to really dig in and cause pain . . . Yay! Being a big guy, you try to be considerate and fold your arms in to give the person next to you as much space as possible, but don't expect that back as they'll spread out and become as wide as possible. Then to distract yourself from the discomfort, you try to use the free in flight entertainment via the United app, but "it's not available right now." In summation either be short and small or be rich and buy the seats with extra legroom when you fly United.

This was probably the worst handled flight I have been on; there was first a slight delay, then a longer delay, then a much longer delay, all of which one could find out only after checking online; there were no announcements about the delay until after the scheduled time of departure; then there was another announcement that there was a mechanical problem and we'll be apprised of the situation at 7pm (the flight was scheduled at 6:25). The person at the counter disappeared. At 7:30, the gate changed to a different flight altogether--still no announcement, still no person at the gate. When a different person finally appeared and I asked her what happened to the Pittsburgh flight, she said, it's here, it'll be departing at this precise gate shortly. At that exact time, the PA system had an announcement that the flight to Pittsburgh is now scheduled at gate 86 at 7.01 (yes, 7:01, even though it was already after 7:30). When we went to gate 86, there, of course, was another flight there. After waiting some more, the woman at the first counter now appeared at gate 86 and said the flight was to be at gate 88. Until the very end when we boarded, gate 88 continued to say the flight was to Columbus. Absolutely abysmal customer service. (Even the boarding was handled badly, but at that time we didn't even care.) I am never recommending Air Canada.

Friendly crew. Coach seats have okay room compared to some other carriers.

At least from my experience, Air Canada is late half the time. This last leg was 6 hours late. No check-in availability notification on the second leg, and I got the flight delay notification after I landed (6 hours later)! Pretty useless. Everything is nickle and dimed with no included food except for the tiny snack thing on a 6 hour flight. It's pretty difficult to get their app to work for entertainment.

The Crew was lovely on the Transatlantic flight. The Dublin-HH crew was polite, one older lady was warm. Of course I would have like free wine, but I imagine many passengers might abuse the offer...

Narrow seats, not spacy feet place (fortunately a nice gentleman in the middle of us, 2 people, found a seat with more space - he was a very long and not too skinny man. Only 3 toilets for both isles of passengers on a TRANSATLANTIC flight.

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.

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.

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

Here's why:

We’re not the seller.

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.
