It is unlikely that you will ever be able to transfer miles from Skywards to TrueBlue. Try calling Emirates, explain your situation and get them to put the miles in the right place now before too much time passes. Good luck with that as the EK agents seem to never have authority to do anything outside of the ordinary.
Supposedly in February 2013, you will be able to use Skywards miles to travel on jetBlue. That said, it has been 8 months already with the Alaska Airlines partnership and the redemption section on the Skywards site still says "coming soon." When exactly is soon? A few years in the future?
Having not flown Emirates now for 2 years, I want to get rid of my 127,000+ miles by using them on jetBlue. Let's hope the February 2013 deadline sticks as it is nearly impossible to use EK miles out of SFO anymore.
