A Technical Upgrade Is About to Disrupt Flights Through Boston, Newark, and Philadelphia

If your flight plans this week route through one of three major Northeastern airports, it's worth double-checking your schedule before heading out the door.

KLM confirmed that an Air Traffic Control equipment upgrade in the Northeastern United States is causing disruptions to flights to, from, or via Boston (BOS), Newark (EWR), and Philadelphia (PHL) between Monday, September 21, and Tuesday, September 22. The airline said it is working to rebook and assist affected passengers, with flexible rebooking options available for anyone holding a ticket issued on or before September 21 — allowing travelers to shift to a new departure date on or before September 25 without additional fees, provided the same travel class remains available.

The disruption reflects a broader pattern of periodic technical upgrades across US air traffic infrastructure, which occasionally require temporary capacity reductions at affected airports while new systems are brought online and tested.

Separately, the International Air Transport Association (IATA) announced this week it has significantly expanded its terminal-level passenger traffic data coverage, growing from 38 to 188 airports worldwide. The expanded dataset gives travel retail stakeholders — airport operators, retailers, and airlines planning terminal operations — considerably more granular insight into passenger flow patterns at a much broader set of airports than IATA's data previously covered.

For travelers with upcoming flights through the affected Northeastern airports this week, checking directly with your airline before heading to the airport remains the most reliable way to confirm whether your specific flight has been impacted by the ongoing ATC equipment transition.
