Given the recent 'enhancements' at CO, I wanted to check some upgradeable fare codes. I generally use Travelocity's pull down 'Site Tools', but for some reason I can't seem to find it on their site. Now, I'll be the first to admit, I could be wrong and it might be on another site (Expedia, ITN etc), so I'd appreciate if any of you can give me a quick refresher course on finding this information.
