Southwest Airlines , the fourth-largest airline in the U.S., is on a strict road to recovery after facing significant reputational and financial headwinds over the last few years.

Southwest Airlines has announced its intention to lay off approximately 15% of its corporate staff. This decision has been described by its CEO as “unprecedented,” amid the company’s efforts to reduce costs. Most of the layoffs will take place at the end of the second quarter of the year.

Southwest Airlines is planning to eliminate an estimated 1,750 positions — about 15% of its corporate workforce — in what will mark the company's first major job cuts in its 53-year history.
