I did a google flight check, picking only "FIRST CLASS" from Calgary to Johanessburg.

Return flights cost between $15K to $20K. Had she booked first class return tickets for $20K without hitchicking with Harper, that would already be outrageously expensive and bad money management.
But Redford spent $15K just to fly from Calgary to Ottawa to join Harper, that was just dumb.
