BTW, United.com recently made a change (within the past week) where reservations with Continental codeshare flights are no longer showing "First (NF)" as the fare class booked along w/ Upgrade: Pending. The reservations now correctly show the coach class that the flights were booked with. Upgrade should still say Pending.
CO Plats are upgraded after UA 1P's. it goes UA GS, UA 1K, UA 1P, CO Plat....
