The article doesn't have the cost for the whole journey by air in June 1939. They quote the price of the transatlantic Pan Am flight, which cost (US)$375 in June 1939 one-way, and from the linked newspaper scan, the round trip was $650, so roughly $12k in current dollars. [1] On the other hand, in June 2018 the cost for a Sydney-London round-trip (a significantly longer route that also faces less competition than transatlantic flights) in first class on Qantas was (AU)$10,700 [2], an equivalent to (US)$7-8k now (depending on whether we take current or historical [3] exchange rates). "First class" nowadays can mean different things on different airlines, routes, and equipment but prices are generally well south of $10k, with the possibility of paying a lot less if you're willing to do your research and are somewhat flexible. This was not an option at the time. I think only the Concorde could compare to these 1939 prices: a NYC-London round-trip would be $13k if it still operated. [4] But other than that, the current first class offerings are less expensive. 1. https://data.bls.gov/cgi-bin/cpicalc.pl?cost1=650&year1=193906&year2=202004 https://data.bls.gov/cgi-bin/cpicalc.pl?cost1=650&year1=1939... 2. https://www.smh.com.au/money/planning-and-budgeting/the-cost-of-flying-first-class-how-can-anyone-afford-it-20180419-p4zait.html https://www.smh.com.au/money/planning-and-budgeting/the-cost... 3. https://www.rba.gov.au/statistics/historical-data.html#exchange-rates https://www.rba.gov.au/statistics/historical-data.html#excha... 4. https://en.wikipedia.org/wiki/Concorde https://en.wikipedia.org/wiki/Concorde
