LOS ANGELES — Flights out of Los Angeles International Airport have been canceled or delayed Thursday because of the deadly crash between an American Airlines plane and military helicopter in Washington, D.C.

Four flights out of LAX were delayed or canceled Thursday.

The midair collision of a Black Hawk Army helicopter and American Airlines passenger jet happened around 9 p.m. Eastern time Wednesday outside of Ronald Reagan National Airport in Arlington, Virginia. There were 64 people on the passenger jet and three military members in the helicopter.

The flight originated from Wichita, Kansas. All on the plane are reportedly dead.

Several of the passengers are reported to be figure skaters and families of the National Development Camp. They were in Wichita for the U.S. Figure Skating Championship.

The crash prompted the closure of Reagan National Airport on Wednesday night. It reopened at 11 a.m. Eastern time Thursday.

All arriving and departing flights in between were diverted to nearby airports, delayed or canceled.
