You can sleep a lot later and get home a lot earlier if you drive. Taking the shuttle sucked balls.Your distance to OKC will be a big factor. I'm in Houston, so only an 8 hour drive so I'll be driving there. But it'll stay parked while I'm there since they have shuttles from most of the housing to the academy.
The FAA will pay you whichever is less. The cost of a plane ticket from where you live to Oklahoma (and back? Without knowing facility I am not sure where the return trip is calculated to) or the driving milage, which I believe is something like 56¢ per mile, no hotels included.Does FAA reimburse per mile or do you have to save receipts for gas? I know I read somewhere that they will pay the cost of driving up to the amount of a plane ticket.
