..I can't understand clearly the following in bold. Please explain them in easy English.
1. Mystique aside, UPS drivers have an enterprise behind them that is a lot more compelling than any love fantasy, though to be sure some of them are quite inventive, such as the Internet blog entry featuring an improvised berth of cushion crating and bubblewrap. I've come to feel that the cult of the UPS driver is actually infatuation with something much bigger than individual drivers or even all the drivers together. It is a cult of UPS's unrelenting commitment to success.
In the above, does "some of them" refer to "love fantasies?" No - to the inventive UPS drivers.
2. Daily Flight Segments: Domestic--1071; International--767
Airports Served: Domestic--400; International--377
In the above, I'm not sure of what "flight segments" mean. It means individual flights = 1071 internal flights and 767 international flights.
