Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

I swear airplane seats keep getting smaller and smaller but everything else was great. Smooth sailing and we got in early.

Separated me and my wife and wife’s sister in far apart different seats even though I booked them all together. Just scams after scams to make us pay more. Worst airline

I have flown on many airlines all over the world, and this plane flight was the most uncomfortable I have ever experienced.

It was delayed then we turned around so not good.

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

Left two hours late, now screens and WiFi wasn’t working. Unacceptable on a 6h gate to gate flight

Original flight was canceled due to bad weather...not a problem, completely understand however I had booked a direct return, instead I was rebooked with a layover of over 2.5 hours. What should have been just over 2 hours turned into 6 hours. Snacks on-board were pitiful and they were constantly out of beverage products.

Not even a snack on a five- hour international flight? Really? One drink serving? Really?

The cabin crew was fine, nothing out of the ordinary. However, the crew at check in was a disaster. We had already checked in and wanted to see if we could upgrade to first class. Waited in line bc the crew was so slow. No sense of urgency. Long story short, the lady, Maria, would refuse to answer our questions directly. As we are about to leave, she asked if we wanted our boarding passes printed. I figured we were there, already wasted time, might as well. We could have gone to through security as we were already checked in. As she’s putting in our information, my bf has to step away, leaving me with out two carry on. I just had surgery and was in a sling as I don’t have much strength or movement in my left arm. She looks down at our carry ons and said we need to make sure it fits. I told her, I haven’t had an issue with it as this is what I flew with from the states to Canada. We both flew with the same carry ons. She just said to me, it doesn’t matter. I also asked her if this is a different procedure with this Air Canada as I have flown to multiple countries and states with this same carry on. She said the same policy apply, which at this point doesn’t seem true since I have gone through multiple cities and countries and multiple airlines with zero issues. I struggled to go over to the stand and once again, struggled to lift my carry on into the rack to see if it fits. All the while, she just stands and watches. Her and the manager both standing there and watching as I dropped and struggle to lift the carry on. My carry on was too wide due to the wheels and they refuse to let me use it. Then, to make matters worst, my bfs carry on, which was clearly smaller than mine, she then asked me to do the same thing, lift it to see that it fits within their measurements. Of course that one fits. But, again, I’m disabled and both the agent and manager stood there, not once offered any help. She forced me to check in my bag with the fee. I should have just walked away because, when we got to the gate, the crew there also asked that anything bigger than the slot gets checked in, FOR FREE. Maria took advantage of my disability, was unsympathetic and just a disappointment to Air Canada. And the manger, that was more interested in making other people’s lives miserable because he was clearly miserable should quit trying to flirt with Maria and actually do his job. What a joke of a staff and what a joke of an air line.
