US airports flight disruption top 4,200: Here's full list of airlines hit by cancellations, reroutes, delays

America’s aviation has been hit by catastrophic conditions on Tuesday, April 21, as three simultaneous crises hit the nation.

The primary reasons for the collapse include TSA staffing collapse, Iran-war fuel shock, and weather restrictions.

As per live FlightAware data, total delays worldwide reached 8,845 on Tuesday, with 675 delays occurring within, into, or out of the United States.

The total number of cancellations worldwide was 421, of which 28 occurred in or affected flights departing from US airports.

San Francisco International Airport became the epicenter of the disaster, with 475 delays and 69 cancellations following the FAA’s issuance of weather-related flight restrictions. Hartsfield-Jackson Atlanta, Boston Logan, and JFK International were the next most affected airports.
