Ever since 9/11 and the GW bush war on terror against the axis of evil days air travel has sucked. Whether intrusive searches or long lines with delays it all got much worse after that.  its interesting to see protocols in other countries.  I remember in Europe everyone (not profiled) was waved down by a wand.  Seems like it would take just as long but they had so many lines because they could station so much security, it was quite efficient.
