Can anyone advise on the best steps and timing for switching from one partner program to another if you're doing e-Miles already? I have close to the 500 point level with Northwest as my mileage partner, but want to switch over to the new offer I just received from HHonors (I guess they are new to e-Miles..). Should I wait till just after I pass the 500 point level I'm close to or just after the points have gone over to Northwest? I would have preferred starting to earn with HHonors immediately but it looks like I might lose all my existing points if I tried to switch over right away now - is that correct? Also, do you have to completely re-register with e-Miles when you change your earning program? Thanks!
