coplatflyer

Apologize in advance if this has been addressed but I could not find.

1) to use a regional upgrade, is there a way to put myself on the upgrade waiting list through continental.com or do I need to call?

2) for system wide upgrade, I understand that the fare has to be W or higher to use the 2011 SWUs. Is there a way to search on continental.com which flights are available for upgrade before paying for the more expensive fare? or do I just have to pay the higher fare and take my chances?

thanks in advance
