backpack with dozens of small metal pins

My backpack has many pins on it to show where all I have traveled. Would American Airlines allow me to carry that with those on or take them all off?

  • Are they allowed through security? – JJJ Jan 22 '20 at 19:29

    AA shouldn’t mind or care. The only issue could have been security, but TSA allows them. – jcaron Jan 22 '20 at 21:18
