In two years I've come to learn the United terminals in a handful of airports like the back of my hand. Curious as to how much time that took, I knocked a spreadsheet together and found myself bewildered. I've missed a few weeks here and there in my timesheet, but I'd say about 90% of the data is there.
|Los Angeles, CA||40||462.00||11.55|
|Little Rock, AR||19||127.75||6.72|
|San Francisco, CA||33||128.75||3.90|
The overall average of 7.81 is, of course, awfully close to an extra full working day per week.
