Flying American? Drop off your bag at the ticket counter for free if you don't want to lug it through the airport. Just check in at one of the bag drop kiosks outside security.
The Terminal Link drivers are your friends especially if your plane arrives at one end of terminal A and your car is parked at the other. They accept tips. It's good karma.
Get dropped off on the arrival level (upper) when you are coming for a departure...the departure level is useless. You just take an escalator upstairs...
There are NO ELEVATORS in the,parking garage so if you have a stroller or are in a wheel chair beware! Try parking on level 1. Also, so much construction makes leaving the airport SO confusing!
You never truly appreciate the airport until you're stuck there at 3 a.m. and you see all the employees that work the graveyard shift to keep this place clean.
