i can't produce numbers but, anecdotally, the idea that 75% of international business travelers get to fly business seems...unlikely based on the people I know and even assuming my own terms are especially shabby. Very frequent travelers, i.e. greater than my own 75K miles per year or so, do get upgrades from time to time but the I dispute the idea that the typical tech business traveler is usually flying business.
