every baggage claim area I saw could be accessed by the general public without going through any security checkpoints. No airline ticket or legitimate reason needed to access these areas at all.
Expert commentators (using the term loosely) talked yesterday about expanding the secured areas of airports, but it seems pretty obvious to me that moving the areas where people queue up for security checks just moves the target areas.
Perhaps the only check is getting a parking stub and having your license plate automatically logged.
I don't get what you mean. I for one would welcome elaboration, by PM if you think it is off subject for the thread.
