The FAA will impose nationwide flight reductions Friday morning as the record-long shutdown strains unpaid air traffic controllers. Forty airports in more than two dozen states, including Atlanta, Dallas, Denver and Charlotte, will see cuts starting at 4% and rising to 10% through Nov. 14. Airlines began canceling flights ahead of the order, with over 780 already scrubbed; Delta plans about 170 Friday, American 220 a day through Monday. Carriers vow to limit disruption by trimming small and medium city routes. An industry analyst warns of a systemwide impact, and package service could slow in Memphis and Louisville.
