DALLAS — Cirium data shows U.S. airline operations held mostly steady Friday, but Saturday schedules near the storm core shifted toward heavy cancellations at several hubs.

Cirium’s end-of-day update (data current as of 5:00 p.m. ET Friday, Jan. 23) showed a limited national impact so far—about 1.55% of scheduled flights canceled systemwide—while warning the disruption escalates Saturday as Winter Storm Fern moves across key corridors.

Highest Saturday impacts center on airports including Memphis (MEM), Dallas/Fort Worth (DFW) and Oklahoma City (OKC), as airlines preemptively trimmed schedules to manage safety and recovery as winter weather threatened wide-area disruption.
