Oh, one thing I noticed at TSA: At the old LGA, all you had to do was with the TSA agent your ID, and they will scan only that through one of their machines (don't need boarding pass). But it seems like they got rid of those machines and now they scan your boarding pass too, like how most airports are. But at most airports where they do this, the scanner is in front and yourself can scan your boarding pass on your own. At LGA now, they take your boarding pass (in this case, my iphone), and scan it themself. I didn't like that the TSA agent needs to grab my phone.
