This is the way to fly:
Singapore Suites Class:
My parents did a lot of commercial flying in the late 1940s.
There was no first-class, because if you were flying, you WERE first-class.
When you crossed the international dateline, you got an elaborate certificate suitable for framing, with drawn images of the four winds blowing, one in each corner (my mom still has one in the family albums).
And all the passengers got engraved passenger lists so they would know the names of the other passengers on the plane.
