If you are in terminal 4, the only TSA pre line is at the C security checkpoint. Good job government bureaucracy! They have the metal detectors turned up too... First time boots have ever been flagged
The chopped salad at Cowboy Ciao in Terminal A is delicious and relatively healthy especially if you leave off the dressing which it doesn't really need. Worth the walk from Terminal C.
Not sure if their tag line of best airport food in America is accurate.. But you will definitely burn some calories walking the endless stretch of concourse between, and even within, terminals.
Don't fly United or US Airways as they suck ass for service, lose your bags & corral you like f%#*@ cattle! Seats suck, no room, charge 4 bags, & generally don't care whether you're a paying customer.
the tequileria restaurant has quesadillas with very little queso in them, not that other alternatives are better. maybe you should catch your connecting flight & get out of this stupid airport.
