American flight AA1671 arrived about 8:30pm on Friday night, and passengers simply got off and left the airport without going through immigration or customs.
A source familiar with the matter said passengers disembarking the plane “just followed” a gate agent. …
“Some passengers on Flight 1671 did not complete immigration and customs process upon arrival when they were inadvertently directed to the domestic terminal,” American Airlines said in a statement.

Apparently American reached out to the 150 passengers and instructed them that they had to return to New York JFK for processing. 144 of the passengers did so. The other 6 are US citizens, and one imagines that some had traveled far from New York by the time they were contacted.

Passengers report the airline is being quite insistent that they return post-haste. It’s not clear to me, though, why they such records cannot be updated electronically and that if they do need to show up in person why it cannot be to the nearest port of entry.
