Reality flights: There is no truth those rumors that I’m a participant in that A&E documentary “reality series” Airline, that goes behind (and in front of) the scenes at Southwest Airlines. Actually there are no rumors yet, but anyone who knows me will suspect I’m in the series as I spend a few days each month aboard Southwest flights. Believe me, this is a reality I know all too well. For the most part, I have positive and predictable experiences with the carrier’s people. I bring the topic up as I will be on Southwest in a few hours (at 6:25 a.m. cst) and will be blog-free for most of Wednesday (unless I run into some wi-fi in DC).
