My screen was broken so now movies, etc, but I didn’t really mind. They did work on it, so good effort on their part.

My screen was broken so now movies, etc, but I didn’t really mind. They did work on it, so good effort on their part.

i was not able to take my flight because the information i needed to book my dog correctly was not provided

They never sent me a confirmation to say my flight time had changed so I cut my holiday short by 6 hours Had to pay over 50 American for my luggage to be checked on the way home and that’s more that it cost on the way there. Arbitrarily charging more for the same thing when the passenger has no options is shady The cabin was an icebox going there and back, if all the passengers have their gloves on and their hoods up that should be an obvious sign to turn up the heat

The Turkish was good . I had a problem with air Transat terrible experience for me

Very good. A lot better experience then I expected for an economy flight.

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

Everything was horrible. On the day of my departure, I was denied check-in and boarding because my reservation only showed one of my last names, while my passport contains both. This minor discrepancy could have been easily corrected, but I was informed that no adjustment could be made. As a result, I lost not only my outbound flight but also my return flight and had to purchase a new ticket at a significantly higher cost.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

The crew were polite and courteous. The Pilot did an excellent landing. It was very smooth and gentle. My only regret is that I was charged twice for my luggage . The attendant gave me no receipt . I didn't realize until I was about to board. How can this be resolved? Thank you.

Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

Vegetarian food option was very poor. Effectively, overcooked rice ("risotto"). Zero protein which is always disappointing with no vegetables and poorly seasoned. Basically had lots of carbs on 6-hour flight. Not acceptable for business class in 2026. Flight was otherwise very good.

Small plane. Tight seating . What can one say except that it was fast!

Flight crew was very cold and stood around a lot talking to each other.

I sat in the first row behind first class. There was plenty of legroom. The entertainment was great. I saw two excellent movies and one episode of a sitcom. Also enjoyed the flight tracker.

Checked in ok for 3 flights at the airport check-in desk, but apparently I was not checked in to my connecting flights even though I was assured that I was and had seats on all 3 flights. Aer Lingus departure was also delayed for 1.5 hours which gave no time to collect bags to go through customs.

It’s my new favourite airline! Everything was smooth and relaxed!

They out me in the baby row so I was surrounded by toddlers, they also did not send my luggage and was not able to book my connecting flight

Westjet never disappoint always terrible small plane ,crowded cheap snack if you can call it snack

Westjet was late and we missed our connecting flight with Cathay. Had to wait 8 hours. Westjet only allows 1 checked in baggage for international flights- it’s always been 2. Canada allows only 1 sandwhich bag size full off small liquids. Everything else will be tossed. Awful trip. Will never fly west jet or go to Toronto to connect flights!

I didn’t have any food but my Prosecco hit the spot. We left on time and the crew was friendly.

I thought the coffee was excellent! The wait for the luggage was acceptable.. It left and arrived on time. My son found that his device worked very well and he really enjoyed his flight! The stewardess moved him up to the emergency exit and he very much appreciated that!

I wasn’t able to book or pay for a seat and they forgot to check me in for my third flight so I spent 24 hours in Toronto waiting for another one.

Everything was good except for flight delay, but it was because of the snow storm in the arrival airport.

The flight was cancelled less than 24 hours before departure. The alternate flight was a day later going from Grenada to Toronto to Vancouver to Calgary to Montreal. 2 days in the air. Not serious, Very bad service

I like the wider seats, Plus lots of legroom, Lacking entertainment, no tv or screen to play with

Liked in-flight wifi Did not like - nothing to complain, really. All good

Fine except for a delay that resulted in our missing the final leg of our flight.

Food was great, I wished there was better options for movies.

737-8 Max is an awful design. Toilets in the rear are inaccessible for most of the flight due to service carts.

Everything but the food was top notch value for the price

Flight was canceled due to labor dispute. Their customer service said I might be ok since strike was on sat. and I was flying Friday. The next morning it was canceled. It can ruin a trip and add stress.

Everything was excellent. Just keep doing what you are. I would travel with this airlines gain.

Flight was good. Really appreciate the second hot food offering. C

The chairs were too upright, but not awful. Boarding was fast and efficient and we did not sit too long in the plane before takeoff.

I didn’t realize booking through Kayak the pricing was in American fees and that I had to pay for my baggage when I arrived at the airport. I thought it was included in the price. For this reason I spent an extra $500. Next time I will book directly through the airline.

Kayak changed my Dublin flight and then changed it back to the original time before I left for Ireland. Unfortunately Kayak never booked me back on the original flight so when I got to the airport I had no flight to London. Very stressful. If I hadn’t gone very early and Aer Lingus staff so helpful it would have been a very wasteful day.

Everything was very excellent The food was great The crew was so nice 🥰👌🏽 I really appreciate and loved travelling with Air Canada 🇨🇦

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Missed flight. Requested assistance for my father and he did not receive it in Paris.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

The flight crew, the on-plane service, and the food were fine. The seats lacked cushioning and were uncomfortable compared to other planes from recent flights. The plane was initially delayed one hour and that expanded to 1.5 hours. When we boarded, there was insufficient room for our carry-on bags, which added more time to disembarking from the plane. It appeared the Air Canada staff or the Toronto Airport staff were less than competent to handle whatever the issue was that caused the delays, which was never communicated.

Boarding was haphazard after people with small children or walking difficulties

Staff was rude in business class. Luggage was damaged and nothing was done about it airlines.

We were helped whenever needed and had a pleasant flight.
