What qualifies an airline to be in *A?
I was wondering -- what allows an airline to become a member of star alliance? For example, when an airline like BM or Ansett joins (which already had some cooperation agreements with UA), what wasn't it doing before that now allows it to be a member of the club?
Is it sharing the reservation system? Agreement on fare levels? Or is it new training for crew and agents? Minimum service standards?
Anyone know?
