The only airline that I've ever encountered that can seem to manage two FF numbers, one for logging in to their www site and one for crediting FF miles is CO (maybe NW handles it as well, but since I always credit my NW filghts to NW, I've not encountered a problem).

There is no need to be logged in to the DL website to purchase a ticket. While purchasing a ticket through DL.com will earn you a 500-mile bonus if logged in, logging in will enter your DL# as the FF#. I don't even know if you still get the 500-mile bonus if you switch your FF# after the purchase, as the bonus isn't credited until you fly.
As a NW Elite, I never once had an problem with my NW FF# number on DL flights, but I always made sure that a DL# was never associated with the ticket (buy ticket on DL.com without being logged in). There are numerous reports on this board that say switching from a DL# to a NW# can be problematic. To me it just doesn't seem worth a potential 500-mile bonus to log into DL.com when purchasing a ticket.
