the passport was last seen in the domestic south terminal in atl by gates T1 and T5. My flight was original from T5 but I had went over T1 to see if i could get on the earlier flight which was unsuccessful. so I went back to Gate T5 upon time to board I realize I couldn’t find my boarding pass and because my seat wasn’t assigned the agent printed a new boarding with my seat assignment. but I it wasn’t afterwards that I realized that the passport was totally not in my possession anymore.
