The seat pocket in front of me was broken. I didn't want to make a fuss but one would have thought during checks pre-flight that should have been noticed and rectified. I was flying with my family including my 4 yr old and we had lots of toys to keep her entertained but had no where to put them apart from on our seats and tables when we were allowed to have them down.

Took a red eye, so slept most of the way. Crew was super chill and let me sleep the whole way. Minor turbulence, but the captain made announcements and made sure everyone felt at ease. Quick to unload passengers once we arrived at the gate. Didn't use the in-flight entertainment but there was a cool and updated map feature that was much better and more high-tech than previous AC flights I have taken. Also enjoyed how the cabin door separated economy from business class, so we didn't have to wait for the entire front of the plane to unload from the same door.

Baggage claim took FOREVER. Air Canada needs to work on this. Waited over 1 hour.

I could not store my belongings near me. No power outlet to charge my devices for my own entertainment on a 7 hour flight. Dealing with constant traffic for the bathroom. I sat in the middle seat between two hours other men. It was a constant struggle arm space. After 7hours in the air I could not wait to get off the plane.

I began asking for my wheelchair escort the minute I got off the plane. I was assured in Houston they would be there when I got to Detroit. They were not. The request was clearly spelled out on my boarding pass along with my personal oxygen equipment information. I kept asking different staff and they would call for me then say somebody would be there. I waited for an entire hour and only when I started to cry did somebody do something. It was terribly stressful.
