Airmail and All-up Letter Rates from 1957

This is an area in which information is very much requested.

It appears that the general structure was for the rates to the British postal area, or other Forces addresses, to be the same as the corresponding rates to the relevant Forces address from the UK (stated explicitly in the leaflets from 1982-97) – but more generally the rates to civilian destinations worldwide were probably not the same as the rates to those destinations from the UK, and appear to have varied by FPO.

Unfortunately, although the surface rates are typically given in the Post Office Warrants and Schemes, the same is not necessarily true for airmail!
