A1. Current Delta Platinum Medallion
A2. At the moment, I have 40000 status miles (Silver); I will have 52000 by the end of this week (Gold), with a return from Japan and a flight to London.
B. I would be happy with Gold, but I already have enough planned trips to reach Platinum. I might even try for elite on another airline (United, Continental, American & Swissair are most likely).
C. I use all three Bay Area airports (SJC, SFO, OAK).
D. 100% success on upgrades on all trips taken this year, plus two upcoming internation trips already ticketed!
