Southwest Airlines held a conference call with investors Thursday to lay out a plan for long-term profitability. The Dallas-based airline posted a profit in the second quarter but losses in the prior two quarters.

The move, including service enhancements and share buybacks, came after the hedge fund Elliott Management called for cost savings and better profits.

Elliott Investment Management LP, the Florida-based hedge fund that has accumulated a 11% stake in Southwest Airlines and pushed for leadership changes, voiced dissatisfaction with the major financial and operational overhaul outlined by the Dallas-based airline at its Sept. 26 Investor Day.

The changes come two days after Elliott threatened to call a special meeting as it tries to push CEO Bob Jordan out.

Southwest Airlines on Thursday unveiled a slew of initiatives to turn around its struggling business, including partnerships, vacation packages for customers and sale-leaseback transactions for aircraft.
