The gambit to solve the staffing issues by moving Newark's sector [1] from New York TRACON to Philadelphia TRACON:

[1] TRACON approach and departure near to a specific airport, ~30-50 miles around an airport, excludes tower, excludes ARTCC a.k.a. "center" or en-route control. Tower controllers look out the window, and TRACON controllers are in a dark room with radar screens.

Original headline: United Airlines says it has 'no other choice' but to cancel flights from Newark airport

> The report said the FAA "lacks a plan to address" the staffing issues, which "in turn poses a risk to the continuity of air traffic operations."

> The decision comes after more than 20% of FAA staff members walked off the job.

I always say I like it when the airlines are in disarray right before I fly for summer vacation. It wakes me up and makes me feel alive.
