Received an email this evening from Westjet asking me to confirm my mailing address for some new vouchers being sent out via snail mail.

No details, other than the subject line: "Plus vouchers and more: please confirm your mailing address".

No indication if it's for all Golds, or if it's because I passed some threshold level.

But it looks like Westjet is continuing to evolve their premium memberships and the whole program, as they suggested would happen last fall. Nice!
