Airport Security Checks

Flying can be a very inefficient form of "public transportation" because of the fear of terrorism.  Last night my husband and I flew to the states from Israel for family reasons.  I was glad that I didn't dirty my socks.  We were not required to take off our shoes.  Other things, no doubt due to profiling, seemed less strict for us.  Maybe it was how I called the security inspector over, asking why we had been skipped.  The atmosphere was pleasant, but I have this way about me that generally makes the security guys/gals feel that I'm just a harmless old lady.

On the otherhand, the Delta people didn't allow water bottles onto the plane.  We emptied the bottle, I drank 2/3 and my husband 1/3 before that strict security check.  It was refilled from the water fountains, but they made us dump it.  At least the Delta airplanes gave large cups of water with unlimited refills. 

When I flew from AZ to NY last summer, I was allowed to bring water and coffee bought in the airport after going through security.  Now I'm confused.  The rules keep changing or is it country or individual airports that make those decisions?

I'd appreciate info, thanks, in the comments.
