Airlines have issued travel waivers to help passengers whose flights into and out of Washington, D.C., were affected following a deadly midair collision on Wednesday.

Aviation experts have warned for years about near collisions at airports around the US, citing air traffic control shortages and airspace congestion.

"I walk here every day. I see helicopters going around. I see planes coming in like crazy. I never thought that would happen."

United CEO Scott Kirby diminished American in comments on Wednesday. American CEO Robert Isom barely responded during American's earnings call.

United Airlines, Delta Air Lines and several other U.S.-based carriers have all given investors strong forecasts for the year.

Wednesday night’s crash of an American Airlines commuter plane in Washington could be one of the worst disasters for the Fort Worth-based airline in more than two decades.

“While performing a training mission a United States Army UH-60 Blackhawk helicopter from Bravo Company, 12th Aviation Battalion, Davison Army Airfield, Fort Belvoir, Va., collided in midair with an American Airlines Bombardier CRJ700 regional jet Flight 5342 last night at Ronald Reagan Washington National Airport," he said.

A jet with 60 passengers and four crew members collided with an Army helicopter while approaching Ronald Reagan National Airport near Washington, D.C., sending the two aircraft plummeting into the Potomac River. Everyone on board the two aircraft is feared dead, officials said Thursday.

An American Airlines flight from Wichita to Washington, D.C. was involved in a crash near Reagan Airport Wednesday night.
