In TIA. The guy in the qatar airways counter was rude. I had to show him my DL too Even though my TPS and AP consist my current address. And be sure that if your boarding pass has 4 SSSS symbol code in it, you will be scanned twice at qatar airways[ no idea abt other airlines]. They said its sierra and you have to go to double scanning. Also you will have to go to extra baggage checking at POE in USA nomatter what. Good luck and have a safe flight.
