Gary at View From the Wing reports that United Mileage Plus and Continental OnePass are now allowing you transfer mileage between the 2 programs as well as combine your elite qualifying activity.  You can transfer miles in 1,000 mile increments once per 24 hour period.  Nothing I can add to Gary’s always excellent analysis except that I just moved a few stray Continental miles over to my United account, and the transfer was instantaneous.  Here’s a link to the elite combination page.  And another link to the mileage transfer page.
