Wasn't able to use my Star Alliance upgrades from any fare within Europe. I didn't see what the difference was anyway -- economy class seating at the front of the plane and higher class free drinks. So I still have these ("Gold" Star Alliance members can use on any non Air Canada flight). Same question applies, anybody having any luck using these. By the way, I checked on the flights that I asked Lufthansa to upgrade me on and there were free seats available in Business Class when the plane took off (what gives with the upgrade you can't use, even when free seats are available?). Maybe somebody is looking out for me and is having me save them for a flight where business class will mean business class seating.
