How do you get google flights to use the new United.com booking page instead of the old? The issue is that you don't know for sure what the PQMs are going to be on the old, while the new calculates everything for you. One of the few changes I like!

Google flights did randomly go to the "new" booking page... once. Can't seem to replicate it.

But it is a very cool trick, using Google flights to accomplish what you can't manage to do by yourself (or on the phone, apparently) with ua.com.
