Our aircraft arrived late into Tokyo from Vancouver, so departure was delayed slightly for cabin cleaning and preparation. After boarding the full flight, we experienced an additional delay due to de-icing, which was an unexpected but necessary step. The pilot advised that the first two hours would likely include light to moderate turbulence, which proved accurate. As a result, cabin service was understandably delayed. This isn’t a complaint — simply a summary of the circumstances. Once we passed through the rough patch, the remainder of the flight was smooth, our pre ordered vegan meals were good and we arrived in YVR close to the expected time. Kudos to the crew for working professionally and diligently throughout the situation. Will fly again long haul with Air Canada.

Everything went smoothly — on-time departure and very organized boarding. We pre-ordered vegan meals, which were fine but not especially memorable. We may have had slightly higher expectations given it was a Japanese airline. It felt like a dinner meal than a breakfast. Overall, it was a good flight experience and we would recommend it.

4.0 Mediocre

Teta, Feb 2026

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

there was no food or entertainment on that short 1.5 hour flight unless you mean the cookie and the overhead announcements... Those Q-400's are the workhorse of the rugged coast and mountains for sure.

6.0 Okay

For the amount of money I spent, I definitely expected a better experience

2.0 Poor

Kendall Lynn, Feb 2026

The last 3 hours it was freezing cold in row 56. Multiple people had their winter coats on and were utilizing the blankets provided by the airline. I also did not have easy access to figure out how to book my food allergy and advance for my meals. Most of everything I received was something I couldn't eat. This needs to be made more accessible. Also, I'm 5'10 which is the average height of the American male. I flew from Philadelphia to Toronto and then to Tokyo and the seats were absolutely unbearable. For that long of a flight it is impossible to get comfortable when doing anything. Flights need to have more space and stop prioritizing costs over people.
