On a different note, what happens when a US1 wants to fly United. US1's do not have any e-upgrades to use in the first place as CP's get unlimited upgrades on US. I would like to try United, it might be nice to experience first class (as opposed to the big seat on US), but I'm unsure on the process.</font>
The reverse. You upgrade at the gate and have to buy special upgrades, probably $50 a pop in line with UA elite pricing.
