If you sign up for the double EQM/EQS promotion by December 15, then all your UA flights and segments from October 25 through December 15, 2005 will be doubled, even if they were earned before you sign up. So if all 10 of your segments were earned in this period, you'd only need 5 more. Note that only UA (including express and Ted) are doubled. Other *A segments count but will not be doubled.

If this is your situation, you might want to look for a cheap segment run to pick up the last few segments and not pay for the fast track.
