Southwest Air Objects to Delta’s Proposed New York Slot Trade

Southwest Airlines Co. and other carriers objected to Delta Air Lines Inc.’s efforts to expand at New York’s LaGuardia airport through a proposed swap of takeoff and landing slots with US Airways Group Inc.

The accord between Delta and US Airways calls for divesting 48 slots to smaller rivals, about 30 percent fewer than a previous plan that those two carriers walked away from last year. Dallas-based Southwest said in a filing that there is “no justification for such smaller divestitures.”
