In theory yes. Always worked for me, but checked today: could not see qcredits. I'm gold, but do not have Qcredits at the moment, will earn 40 next week. Does that mean I can not see it because I don't have QCredits at the moment? Or could it mean there is no chance to upgrade the routing I want with QCredits?

Basically I'd like to upgrade from Eco to Biz from VIE/ZAG to DOH or from DOH to BKK. Would have been interesting how much I need for both sectors...I assume it's more than 40...

Does upgradability with QCredits also depend on the Economy booking class?

thx for your help...
