Passenger fares on Imperial's single-class services clearly played a role in determining who flew, and how flying served and projected Empire. Imperial Airways kept statistical records fastidiously. Flight incident reports show men out numbering women on Imperial's long-haul flights, but the ratios were not static. British women passengers were generally given only vague identity if they were unmarried. Foreign royalty were among the most celebrated passengers in the publicity Imperial gave to celebrity passengers. The Indian air route had its share of notable passengers. The Vicereine flew back to India on Imperial after four months' home leave in 1933. Professionals with other paid careers also used Imperial Airways to move about. Surgeons, scientists and scholars were among the first converts to commercial air transport. People connected with Imperial Airways and those conducting aviation negotiations or doing airline business also travelled about the Empire by air.
