Hi,

Does anyone know if it is possible to use an AC SWU on an AC/OS ticket from YHZ-YYZ-VIE-SJJ and back?

I am flying YHZ-YYZ on AC, then YYZ-VIE-SJJ on OS. I wouldn't bother to use an upgrade cert from Halifax to Toronto, but would like to do so across the water. If I use the upgrade to check in to YYZ, would there be any chance that the upgrade would follow me?

AC told me that I couldn't use the cert unless it was AC metal across the water, but I wonder if OS might be a bit more lenient.

Am flying tomorrow (Aug 30), so if anyone who has any insight reads this, could you answer fast? I'd be grateful for any help.

Thanks,
karen
