I signed up for E-Miles with NW and my recent 500-mile transfer occured rather timely without any problems to WP. Too bad I cannot 'switch' e-Rewards from DL to NW. I signed up for that in the beginning through a DL promo so now I'm locked in but don't bank SM miles since NW is ST partner.
Before you suggest it, I have considered opening a new account to a separate e-mail account but it appears in their TOS that this will lead to cancellation of all points. I usually only redeem HH points but did do a DL miles transfer to have activity for the few miles still sitting there. You never know...I usually have enough activity to keep the balance higher than my maximum redemptions to the programs I use. I'm not a power shopper so the percentage off deals don't really tempt me much.
And for the post about not ever going on vacation in VA, well, you don't know what you may be missing. Virginia is for lovers, after all.
