Thanks for this!
looks like I will have a econ seat in W.. I am not sure if it works but in UA.COM search when I choose the drop box to SWU Region 2 it says the flight is not eligible for upgrade. Does that mean upgradable openings are full and I can still request and waitlist?
What is I, NC and Y and C, I never could figure this out. Is there a site that defines the class.
