I recently waitlisted and cleared 4 SH/Europe upgrades: two for flights next month, and two for flights in August. I have noticed only 2 vouchers debited from my account (for the flights next month, presumably). My tracking period ends at the end of May.
Shouldn't I have 2 more "current" Europe upgrades pulled? Or will those not be pulled until I get a new batch of upgrade vouchers when my tracking period resets?
