Southwest Airlines is set to significantly reduce its service and staffing in Atlanta, slashing flights by a third and cutting over 300 jobs as part of a cost-cutting strategy to address lackluster profits. The airline is responding to growing pressure from activist investor Elliott Management, which is pushing for a special shareholder meeting aimed at potential leadership changes. Executives have warned employees of 'difficult decisions' ahead as the company prepares for major operational overhauls in light of an ongoing feud with investors. This drastic move at one of America's busiest airports highlights the airline's efforts to stem losses and revamp its business model amid a challenging financial landscape.
