in the real "good ole days" of Southwest, when they flew only intrastate (Texas)...SAT..DAL...HOU...., they didn't have to abide by the "wait till you get in the air, before you could drink" rules...on occasion, you could walk on the plane, and there was a washtub filled with ice and Lone Star or Pearl longnecks...help yourself..of course, I am sure some beer "afficiandos" would be insulted with that choice..
those were the days when your cash register receipt from the ticket counter, was your boarding pass...the figure $16 bucks come to mind..
