When I try and do this after logging in I have a list of pax that I can select from, limited to the members of the Household account (HHA). It may be this that's the problem? You can get around it by inviting Miss DrP to join the Exec Club as a member of your HHA (just supply your email address). If you don't want to do this you'll probably have to call them unless anyone else can help? I've never booked an MFU for anyone that isn't in my HHA.
