(All as a silver)
5/21 all on el cheapos
1/1 on eligible reward flights (SAP-IAH)
Upgrades were:
IAH-YVR
YVR-IAH (thanks CO.com specials!)
IAH-ORD (early early Sunday morning)
AUS-IAH (just got lucky I guess)
DEN-IAH (was early Sat. AM I think?)
Looking forward to a little better ratio as a gold next year!
