<< With the increased security, you're safer now than before 9/11. Allow plenty of time, don't take any scissors, nail clippers, knives, etc. with you (if you must take any stuff like that, check your bag instead of carrying it on), wear good socks in case you get selected for a more detailed search. Be patient, sometimes there a long lines. If you allowed extra time, you won't be stressed. >>
Very good advise.
Last week I flew to Washington D.C. Actually, we flew into BWI and drove to D.C. - tickets were cheaper. Make sure that you don't have anything metallic on you when you go through the metal detector. If you do then they "wand" you and search your bag. That happened to me once. If you don't set off the metal detector, you go right through unless you get picked as a random search - in my experience. And by all means, never leave your bag unattended. I saw a guy get the royal treatment (had to take his shoes and belt off and completely empty his bags) when he left his bag unattended.
I was not necessarily nervous but more alert as to my surroundings. I doubt you'll have any problems. Try to have a nice trip.🙂
