The problem is every time i check with star alliance desk they tell me the flight shows full but copa is asking in an email to bid on an upgrade on those very same seats. Is it full or is space available and if it is available it is against their policy not to upgrade my ticket before bidders.

20. What are the criteria for determining an upgrade to Business Class?
Upgrades to Business Class are not guaranteed. They will first depend on the seats availability after all courtesy upgrades of Premier Members have been given. And, afterwards, on the offers that are received.
