As I snapped up a $138 MKE-SEA fare for a quick MR and visit to Boeing in a few weeks, I'm curious to try using EasyCheckin at ORD (to get the 500 bonus miles, of course), and then drive on up to MKE to board the plane.

Do you think this will work? Or are Easy Checkin modules "intelligent" enough to know I'm checking in at the wrong airport?
