By my reading of the rules, if you book a vacation package through continental.com, then you are not eligible for an upgrade. Is this a rock solid rule? (i.e., has anyone been upgraded in such a situation?) Applies to both domestic and BF upgrades.
This summer, we turned down the EWR-NRT promotion because they would not consider us for upgrades (miles + $400/segment).
I think one would be eligible for BF upgrades with the current EWR-HKG promotion? (seat availibility might be another thing).
