FT friends: I am traveling DEL-EWR end September 2013 and returning EWR-DEL in the first week of October 2013.

I am booked in B-Class and applying two GPUs.

I am anticipating clearance of both upgrade waitlists before the dates of travel, as I have been 100% successful in 2013 .

My waitlists have, so far, always been for "R" to become available. When I today hovered over the DEL-EWR upgrade arrow, I see:"Upgrade to United BusinessFirst for this flight requested using a Global Premier Upgrade.".

Checking the return flight EWR-DEL, it reads: "You are confirmed in B class on this flight and have requested a change to PN class. You will be automatically confirmed on this flight if space in your requested class (PN) becomes available."

This is the first time I see a PN wait list. It was always "R": Upgrade with Miles/GPU/RPU/CPU R/RN. According to Expert Flyer: "PN" is an upgrade from B/M Class for Elites. It is also odd to see two applied GPUs in the same reservation resulting in both an "R" and a "PN" request

I guess as a Mileage Plus Elite member, I should have always been PN wait listed. Is this now finally what is being enforced? So no longer "R" wait listing for me, but "PN?"
