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.

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.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

Great flights. 90 minute departure delay for maintenance issues, not a great start but, afer that very good. Didn't pay extra for seats and lucked into a window and an aisle seat. Price was excellent at the super low economy level.

Just a little improvement on food but everything is excellent

Everything was fine, crew was great. Always appreciate an on-time flight.

They lost my checked in luggage, why do I pay for my cargo not arriving at the same destination as me?

Poor planning meant the plane was delayed an hour, then a thunder storm started and the ground staff couldn't work. Eventual arrival in Santiago was 3 hours late resulting in missed connections and the need to buy new tickets.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

The pork noodles were disgusting. The tuna sandwich had hardly any tuna and the bread was stale. A salad would have been better. An apple or a muffin.

Air Canada is the worst but the only option for my route
