1983(c)- A few days before you’re due to finally wrap up the Guam project, you receive a call from another client’s representative in Macao asking you to lead a team-building workshop for five of their staff. The client will host a reception at the conclusion of the workshop on Saturday, after which the six of you will proceed to Rio de Janeiro to meet their project manager at a Monday luncheon that will kick off a week of planning meetings.
It will obviously be a long trek to Brazil after the workshop, but you’ll only have to change planes once. It’s even possible that you’ll be on the same jet for both one-stop flights. Airline, equipment, and routing please.
Macao in 1983 didn't have an airport, but the usual way was to take the high-speed ferry across to Hong Kong (within sight), where the old Kai Tak airport provides a departure point.
If it's possibly the same aircraft then what about Japan Air Lines, on a 747, initially say Hong Kong-Osaka-Tokyo, then onward Tokyo-Los Angeles-Rio.
