Cirium: Snowstorm Cancellations Surge Into Saturday

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.
