You can also call, but as I'm YYZ-based, didn't want to be put on hold for a longer period of time. I imagine they'll set up an office in YYZ once the YYZ-CAN flights start.

Phone: 001-604-638-8866
Fax: 001-604-638-8867

Provide them with your ticket #, booking reference, name (just to head off the verification tag game).

I had the seatmap open, and just owing to the fact that the seats may be scooped up by others in the time they need to respond, I gave them a range of acceptable seats. For example, 1A, 2A, 3A in whichever order I desired.

Hope that helps, and happy travels!

I've never flown CZ before, and am looking forward to my PEK-CAN-BKK trips next year!
