Southwest Airlines probing pilot's use of anti-Biden phrase on plane's public address system

Southwest Airlines said Sunday it's conducting an internal investigation after one of its pilots used a phrase that's become a stand-in for insulting President Joe Biden during the pilot's greeting to passengers over the plane's public address system last week.

The airline announced its investigation after The Associated Press reported the incident in a story about the growing use of the phrase "Let's go, Brandon," an aphorism in conservative circles for a vulgarity targeting Mr. Biden.

The pilot's use of the phrase drew audible gasps from some passengers on the flight from Houston to Albuquerque on Friday. An AP reporter was on the flight.
