Thank you!!

Great thanks~

I'm looking at upgrading a flight w miles + cash. One of my flights has the option to upgrade but I can't select each leg individually. Does that mean if the upgrade clears, it will apply to the entire trip (Lis to erw and erw to sfo) or is it possible only one leg will clear?

When I've done this before usually I see a (?) with the different possible outcomes but that's only been for pp or Polaris, not for multiple legs. this is my first time dealing w this would love people's insight.
