The BA591 LHR-JFK-LAX-HNL-NAN-SYD.
Crew either came back same route or went home via the East.
The Captain referred to in the story who insisted on being called Captain G*****Sir was on VC10's and was extremely unpopular with everyone so much so that he would not put his suitcase in the hold as it often got lost or squashed or left on apron in rain.
The Sydney through the west was so popular with crew that legend has it one crew had 591 tattooed on their bums!
