I just submitted a request to have United match my Delta Plat. status and they just did it for the 2nd time (First time about 4 years ago and never used it) and they just awarded me Executive Premier for the next 90 days. In order to keep that status next year I need to fly 15,000 miles or 30 segments in the next 90 days. If I do so I will make EP for all of 2010.

is where I sent the request and it took about 3 days for a response.
Good luck!
