This is probably a silly question, but I didn't find it (admittedly I just skimmed the beginning and ending of the thread): If I check on expertflyer for a fare, it typically doesn't include the phony "fuel charges." Will I be assessed these charges on a RTW explorer? If so, on what basis is it assessed:

a. Airline who books the ticket.

b. On a segment by segment basis.

c. Based on which airline flies the first segment.

etc.
