Wow! So the TSA is making up a new thing by asking about two pairs of pants on you? - but not following their rule of checking BP's for flight origination - the guy who had a JFK BP but was at LGA.
Lines are longer everywhere these days. Lots of airports have that terminal that's infrequently used - that connects to everywhere else in the airport, but I find nowadays there is only one screening point at those points, putting you at the mercy of some dumb9sss who doesn't understand how metal detectors work, etc....
