Published on January 4, 2026
Travel across the US is in chaos today as American, Delta, United, Southwest, and other airlines report over 1,000 cancelled flights and more than 6,000 delayed flights. This massive disruption is affecting major airports in cities like Atlanta, Chicago, Los Angeles, New York, and many more. Airlines are struggling to keep up with the volume of cancellations and delays, leaving passengers stranded at key hubs. Weather conditions, ground delays, and airspace flow restrictions are contributing to this widespread disruption. As a result, both domestic and international flights are facing significant setbacks, causing frustration for countless travelers.
The impact on the US travel network is far-reaching, with ripple effects felt in airports across the country. For passengers, these delays are making an already stressful journey even more challenging.

Causes of Disruptions: Weather, Ground Delays, and Airspace Flow Restrictions

Deicing Operations and Weather Impact

• CAK (Akron-Canton Airport): Deicing operations began earlier, causing delays as planes undergo necessary procedures to ensure safe takeoff in icy conditions.
• DTW (Detroit Metropolitan Airport): Similar deicing operations are causing delays at DTW. In addition to the deicing, the airport is also experiencing ground delays due to low ceilings, contributing to an average delay of 99 minutes. These delays are likely to continue as weather conditions fluctuate.

Ground Delays at Major Airports

• MCO (Orlando International Airport): Passengers departing from Orlando are facing departure delays, with an average delay of 15 minutes that is expected to increase. The delays are attributed to team initiatives and other operational issues, which are slowing down the movement of aircraft.
• OPF (Opa-locka Executive Airport): This airport is seeing much longer delays, with departure delays averaging 120 minutes. These delays are also linked to operational team initiatives and volume control measures.
• SFO (San Francisco International Airport): SFO is experiencing ground delays due to high winds, with average delays reaching 154 minutes. Wind conditions are causing disruptions to both departing and arriving flights, resulting in a backlog of aircraft at the airport.
• SUA (Sarasota-Bradenton International Airport): Ground delays are also affecting SUA, with delays averaging 133 minutes due to high airport volume. This is creating congestion at check-in counters, security lines, and gates, exacerbating the situation for departing passengers.

Airspace Flow Program and Equipment Outages

• FCA (Flow Constrained Area): Flights crossing through the FCA are experiencing an average delay of 77 minutes, or being rerouted due to airspace volume. The flow-constrained area applies to southbound departures, affecting both domestic and international flights.
• FCAPSP: Another airspace flow program is causing substantial disruptions. Flights destined for Palm Springs (PSP), Thermal (TRM), and other areas are delayed by an average of 530 minutes or rerouted due to an equipment outage. This has been compounded by communication issues affecting the status of flights.
