It should also be noted that one of the things which makes Singapore Changi International such a great airport is superb security organization. You don't even know you are being watched and profiled. Each gate has its own security clearance as people assemble to board. You will occasionally get wanded a second time, but generally by a beautiful shapely Asian girl who is about as pleasant as your typical unionized TSA slob is unpleasant.
I like Midway. I find it much easier to get in and out of than O’Hare.
