Oh, 15-30 minute TSA wait is the worst case scenario? That's pretty pud.
Also, there are so many waits at an airport other than TSA wait, why worry so much about that one?
I think that is the common scenario. I think I posted about my 75 minute wait from January ITT.
What other waits are there in an airport? Waiting for the bartender at the lounge?
Wait for long term parking shuttle after parking car, wait during shuttle ride, wait while others exit shuttle, wait to check in and/or check bag, wait while riding escalators/conveyors/trains to terminal, wait in terminal for boarding, wait for everyone to eff with stowing their crap and sit in their seats on the plane, wait for the rough ridin' slow ass pilot to start driving, wait on the runway behind seven other slow ass pilots until you are rough ridin' cleared for rough ridin' take off, wait for-rough ridin'-ever for them to open that goddamn door, wait for everyone to retrieve their crap and deplane, wait for baggage at the carousel, wait for the rental car shuttle, wait in line for the rental car counter, wait once you are at the rental car counter, and wait to pay for long term parking before leaving.
