Well, I have just completed 4 flight segments. My mother, girlfriend and others have all flown in the past 3 weeks. There are no problems. It does take just a little more time to check in because of the lines. I sure do miss curb-side checking of baggage, but they tell me it's coming back. Yesterday at Dullas, they didn't even check my ID at the security station. I could have gotten my ticket and handed it off to someone else. I was wanded 3 out of four times going through security but that is nothing new. They never asked me to turn on my cell phone, that used to be a favorate. One person did notice that my drivers licence has expired. I told him that it didn't mean I had expired, (I showed my passport instead.)
The only way to increase security is to 1. screen all luggage, 2. ID everybody at the ticket counter and aircraft door, 3. Airlines will start having to profile their passangers. I don't see any of this happening so I guess it will be business as usual very shortly.
