Passengers off of flight AY9 “walked to an exit, and followed a TSA Agent through the door leading outside.” One passenger reports realizing the mistake and finding “he went to an agent in the Customs and Border Control (CBP) office [who] told him to not worry and “just go ahead.”
CBP blames Finnair because “it’s up to the airlines to make sure passengers go from an arrival gate to customs” while TSA “says it’s CBP’s responsibility.”
