Ok, I am just curious here and I know Delta would never publish this..but am interested to hear your thoughts:

For International BE, are most people buying these tickets outright, or is it mostly YBM fare plus SWU, skymiles redemption, or non-revs? Is it truly fragmented or heavily skewed towards one or another?

Are most people who are purchasing BE tickets on their company's dime for work, or simply in a financial position to be able to do so for their own personal trips?

I know this is impossible to know exactly but thought some of you might have some insight.
