Like many others here I presume, I expect to become a newly minted Executive Platinum next month. I'll have several existing itineraries booked into the future and would like to make sure that my new (EXP) status rather than my old (PLT) status is properly reflected. I seem to recall that this does NOT happen automaticaly, and that it is not as simple as removing a frequent flyer # and then re-entering it. Does anyone know the proper procedure? Thanks!
