I flew at Christmas this year, returning on 1/3. We fly out of a small airport, but I was surprised by how careful they were about the luggage that was checked. After we checked in at the counter, we had to take all the luggage, including the checked luggage, to be scanned. They wouldn't let us near while they were scanning, either. If you had food or anything else beyond clothes in your checked luggage, they opened the luggage and searched it by hand. They searched my purse because I had needlepoint in a bag in the purse. The man in front of me was searched--very carefully--because his jeans zipper beeped. He was quite embarassed because they had to have one of the security people put his hand down the man's pants to check for contraband!! Actually, I found Orlando to be less stringent on rules--for example, my luggage arrived 11 hours before I did(that's a different story), and my daughters found them just laying there against the wall for anyone to pick up, which they did, and brought it to us. By contrast, our local airport, had our luggage under lock and key, and I had to show ID and baggage tickets to get it just one flight later. So it all depends on your local airport, but Michigan seems to be taking the regulations very seriously.
