I was rescheduled when I missed my flight due to border clearance issue

I was rescheduled when I missed my flight due to border clearance issue

Flight was delayed twice which made our arrival extremely late (actually into next day). Not an easy travel. But when we requested assistance for boarding we were really impressed with how they helped us! Strongly praise their assistance.

It was out first time flying Air Canada and it was ok, comfort-wise. I hope airlines are able to get a quiet room installed for young children flying. Screaming and crying the whole time in business class is quite unfortunate. That was the only thing that really messed up the experience.

Received an email a few hours before boarding that wifi and seatback entertainment would not be available. There was no explanation for this. We were served 1 x 20 gram granola bar as a snack (not even a full granola bar) which was really embarrassing. The crew was lovely (none of this was their fault) and the flight was successful, but the aircraft itself was falling apart on the inside. Overhead comfort control panels were worn and some were hanging out and non functional, This aircraft needs to be upgraded.

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing

Staff were very friendly. Plane left on time and arrived on time.

Delays. Poor support booking a hotel after a diverted flight.

The Air Canada AC1 flight from Toronto to Tokyo on May 16 was great overall. Service, crew, food and entertainment were all excellent and everything ran smoothly. We had emergency exit seats so legroom was amazing, but the seats themselves weren’t very comfortable and the plane feels like it could use an upgrade for a long-haul flight. Aside from that, everything else was perfect.

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.
