NEW YORK: Veteran American Airlines Chief Executive Doug Parker plans to step down in March and will be succeeded by his deputy, Robert Isom, the carrier announced Tuesday.

A longtime fixture atop US carriers, Parker led US Airways prior to its merger with American Airlines in 2013 when he took over the combined company. He will step down March 31 but remain chairman of the board.

American’s leadership transition was delayed by the Covid-19 pandemic “and the devastating impact it had on our industry,” Parker said in a letter to employees.

“While we still have work to do, the recovery from the pandemic is underway and now is the right time to make the transition,” Parker said.

American entered the pandemic downturn with more debt than rivals, but has benefited from federal support programs, as well as ready access to public markets amid low interest rates. Like other US carriers, American’s financial position has improved over the last 18 months, as air travel has gradually ramped back up.
