Travel effects

All civilian airplane traffic in the United States was grounded until Thursday, September 13. United Airlines cancelled all flights worldwide temporarily. First stranded planes were allowed to go to their intended destinations, then limited service resumed. On Thursday night the New York area airports (JFK, La Guardia, Newark) were closed again, and were reopened Friday morning. The only traffic from La Guardia during the closure was a single C9C government VIP jet, departing at approximately 5:15PM on the 12th.

All train service through Union Station was suspended.

Beginning September 27, one-occupant cars were banned from crossing into Lower Manhattan from Midtown on weekday mornings, in an effort to relieve some of the crush of traffic in the city (the morning rush hour was lasting from 5:30 AM to noon), caused largely by the increased security measures put in place.
