American Air Flight Attendants Call for CEO Isom to Step Down

American Airlines Group Inc. flight attendants called on Chief Executive Officer Robert Isom to step down as the carrier grapples with operational and financial underperformance.

The board of directors of the Association of Professional Flight Attendants issued a unanimous vote of no confidence in Isom on Monday, according to a letter sent to the union representing 28,000 flight attendants. The move marks the first time the union has ever taken such action against an American Airlines head.
