Pan American First Flight Houston Texas - Tokyo Japan - Round the World

Description

In the 1977-78 Transatlantic Route Proceeding Pan American acquired Houston – previously a gateway
to Mexico and Latin America over Foreign Air Mail Route 5 – as a co-terminal on its transatlantic route. In mid-1978 the
airline took the first step to make this city a major international transportation hub by extending its
round-the-world flights from the previous New York terminus.
