We stood for a long time beyond the gate before any boarding occurred. Other than that, it was fine. It helped that it wasn't a full plane.

We stood for a long time beyond the gate before any boarding occurred. Other than that, it was fine. It helped that it wasn't a full plane.

Like- beer/wine for free Dis-like- all other aspects- customer service was horrible the entire trip. No help from Air Canada after they changed flight 6+ hours later. Also they put us on standby for no reason. Then almost 2 hours to get our bags after we arrived back at airport

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

This was actually a bus ride to the KW airport. It was smooth and comfortable and on time.

The plane in use lacked an entertainment system (perhaps because it was still being updated?). It was an overnight flight so it wasn't terrible but still. The actual seat was adequate but not great. As an economy flyer, food review is largely irrelevant. I am unhappy with this race to the bottom for services provided especially as it applies to baggage restrictions.

I arrived at destination, two hours late. For lunch we had cookies and almonds.

The plane seats were very uncomfortable, hardly any padding left and very narrow, Makes a long oversea flight very difficult. The food is served with minimal space so its hard to eat. They really need to have planes with more room for overseas!

Good overall but I’m 5’10 and seating is always tight

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.
