On Jan 22, two flight attendants on a Delta Airlines flight from Los Angeles to Minneapolis started disagreeing on some in flight procedures and then engaged in a fist fight, the purser informed the flight deck and the captain decided to divert.
The aircraft was then diverted to Salt Lake City and remained on the ground for about 80 minutes, it then continued to Minneapolis with a delay of 75 minutes.
The airline subsequently sent a letter of apology stating: "... some of our team members did not display their best behavior. We expect our flight crew to be nothing but courteous and professional at all times and what you experienced was far from that. I am sorry we didn’t deliver on our brand promise for you today."
They should have been listening to Ludovico Einaudi - Ancora, it will always put you in a better place.
