Posted : Geneve Aug 4, 1941

Probable Route : Geneve to Marseille to Lisbon, probably by rail; FAM 18 Atlantic Clipper to New York; USA domestic airlines to San Francisco; FAM 19 from San Francisco to Auckland; TEAL from Auckland to Sydney; Australia National Airlines - ANA to Melbourne.

Notes : The intended general routing was marked by a Postal Clerk in blue crayon - Geneve Via Lisbonne & France, indicating service through France (possibly by rail) to connect with Pan Am's two-ocean Clipper service at Lisbon. According to the Boyle book, the 2.00 Swfr rate paid for service from Geneve to Rome by rail, to Barcelona via Ala Latoria, to Lisbon by IBERIA, and then Pan Ams two-ocean service. Without transit markings, it is difficult to determine the exact route, so we went with the routing marked on the cover as the probable route.

Rate : 2.00 Swfr = .30 base rate + 1.70 air surcharge
