What is the policy on using SSWU on AC codeshare flights operated by another Star Alliance partner?
In specific I refer to YUL-ZRH on AC/Swiss?
Thanks
You could try going to the source... the SSWU itself:
Validity > Transferability
• All schedule flights operated by Air Canada or Air Canada Jazz™.
Air Canada code-share flights operated by other airlines and charter flights are not eligible. Standby upgrade requests at the airport are permitted for Star Alliance™ codeshare flights operated by Air Canada.
