This is my first post on FT although I have been following a few different forums.
Cathay Boy, thanks for your description of your ORD experience. It is helpful for me as I am flying out of ORD on CX for the first time next month. You mentioned going through metal detectors at T5. I thought they had AIT installed there. I am stressing a little about the AIT/pat downs because of horror stories I have read. It seems like the easier thing to do would be just to subject to the AIT instead of opting out but I haven't even allowed my dentist to do diagnostic x-rays on my teeth for years! I would rather minimize radiation exposure until these AIT machines have been tested in use for at least 5 years. Do you have a choice of metal detector or AIT at T5 and T3?
