1 hour late No hot drinks No restroom in the back of the plane

I did the posting for 45 years. I just retired. I’m the only seat in the plane but didn’t have any phone. It has to be mine so imagine seeing 13 hours on the flat seat with a belt that didn’t close all the rest was OK.

I had wonderful wheelchair assistance through the Montreal airport onto the flight. Air Canada was excellent in this both at the Fredericton airport and the Montreal one where an attendant helped us through customs as well as transport and baggage security.

Flight was cancelled last minute due to Air Canada strike leaving us stranded and having to stressfully find a way home that cost hundreds of dollars in excess cost added to the trip. Having just experienced our mother's funeral service, this was not a good way to end our trip.

They went on strike before time and screwed us big time. Which is not fair. We respect their planned strike but why they went on strike ahead of time ??? Poor garbage management

Premium Economy is best if you can't get upgraded to Business.. Not as good to sleep for red-eye flights, but does the job. More space for your legs and arms.. The food is also better and the service is almost like business.

Awful. As we were boarding we were told the flight was cancelled. Then had to stand in a queue for 3 hours to talk to someone at the kiosk of Air Canada. They were not helpful at all. No empathy. My issue is not with them striking but the total disregard for the chaos and distress late notice caused. No thought on the impact this has caused.

Horrible, experience, 5 hours delay, they changed gates 3 times, the last one we had to wait for 1::30 hre for the door to open to get to that gate. 0 apologies from Air Canada, they don’t care at all about their passengers

I had a very disappointing experience with customer service. I was suffering from a severe viral infection that included a rash and persistent cough, leaving me unable to even sit upright. Given the circumstances, I requested travel credits from Canada Air, explaining the potential health risk to others onboard. However, the airline showed no concern for my condition and stated they were not in a position to make decisions based on health considerations. Despite my illness, I received no support or flexibility. Ultimately, I chose to forgo my flight due to their lack of responsiveness. It’s unfortunate that airlines like this operate without prioritizing passenger health and safety.

On-time boarding, departure, and flight. Electronic notifications about bags for the whole of their own journey too - from when they got accepted into the system through to being loaded onto the plane and then finally being disgorged onto the right carousel. That was an excellent feature.
