The "frequent traveler surcharge" or whatever they call it, depends on which program you choose to collect miles/points with. Some, like DL are something like .60 for a week and others like Club Carlson can be way more. Most of the foreign FF programs aren't charged the fee. Just play around and see which one of your programs make the most sense per point/mile.
