Alarms sounded in the cockpit of a Southwest Airlines jet shortly after taking off from Hollywood Burbank airport near Los Angeles on Friday, prompting evasive maneuvers, the airline said in a statement.

Passengers aboard a Southwest Airlines jet from Burbank to Las Vegas said their pilot had to “aggressively” dive to avoid a midair collision with another plane shortly after takeoff on Friday afternoon.

Two flight attendants on a Southwest Airlines Co. jet were injured Friday after the pilot had to maneuver sharply in response to alerts that another aircraft was in the vicinity.
