‍DALLAS — U.S. airlines canceled 803 of 21,748 scheduled flights this morning, an overall 3.7% cancellation rate, according to aviation analytics firm Cirium, with data updated as of 8:45 a.m. ET, Saturday, November 8, 2025. 

American, United, and Delta account for the majority of cancellations by volume, with patterns clustering around Charlotte (CLT) hub operations, Denver–Colorado Springs, and select Northeast–Florida and capital corridor markets. (Source: Cirium)

Worst-Hit Routes (today)

• Denver–Phoenix (WN): 3 cancellations out of 7 scheduled (~43%).
• Charlotte–Orlando (AA): 3/9 (~33%) each way (CLT–MCO and MCO–CLT).
• Colorado Springs–Denver (UA): 3/9 (~33%) each way (COS–DEN and DEN–COS).
• Charlotte spoke routes (AA): 2/6 (~33%) on several CLT spokes, notably CLT–ORF, CLT–TRI, and DFW–GRK / GRK–DFW (AA).
• Northeast–Florida (B6): 2/6 (~33%) on BOS–FLL and JFK–FLL pairs.
• Capital corridor shuttle (UA): 2/6 (~33%) on DCA–EWR in both directions.

Airport Impact

• Highest cancellations by volume: CLT (63) leads by a wide margin, followed by ATL (37), ORD (37), DEN (29), DFW (26), MCO (20), PHX (20), JFK (19), DCA (18), EWR (17), LAX (17).
• Highest cancellation rates (≥50 flights): CLT ~9.2%, ORF ~9.2%, CMH ~7.8%, BUF ~7.5%, BUR ~6.0%, BHM ~5.9%, MCI ~5.7%, PIT ~5.7%, DCA ~5.7%.

Airline Impact (by cancellations)

• American (AA): 292 cancellations (~5.3% of 5,485 flights).
• United (UA): 173 (~4.2% of 4,088).
• Delta (DL): 160 (~3.9% of 4,095).
• Southwest (WN): 83 (~2.7% of 3,132).
• Alaska (AS): 33 (~3.1% of 1,079).
• JetBlue (B6): 22 (~3.3% of 657).

Regional Patterns

• CLT-centric ripple: Elevated cancellations on Charlotte spokes (to MCO, ORF, TRI) suggest localized hub constraints driving disproportionate impact in the Carolinas/Mid-Atlantic.
• Front Range pairing: DEN–COS disruptions cut both ways, pointing to operational imbalances in the Front Range.
• Northeast–Florida softness: BOS/JFK–FLL pairs show notable trims (B6), consistent with a leisure-heavy corridor absorbing tactical reductions.
• Capital corridor blips: DCA–EWR cancellations (UA) indicate potential ATC/flow management or crew ripple on short-stage sectors.

Outlook for Sunday

Cirium indicates no material change is anticipated for Sunday’s schedule based on current trends; if conditions shift, a revised view will follow in a subsequent update. In practical terms, that implies steady-state pressure levels around CLT, selective short-haul corridors, and Front Range pairings, unless weather or ATC constraints materially change.
