After departing from Burbank, traffic alerts required a Southwest Airlines flight crew on a Las Vegas-bound plane to "climb and descend to comply with the alerts," according to an airline representative.

A person on the flight said it “dove aggressively” and that people flew out of their seats. The flight landed safely at its destination, Las Vegas.

One person on the flight said on social media that some passengers “flew out of their seats and bumped heads on the ceiling.”
