The leadership changes come after the airline's executive chairman was pressured to retire early last year and two-thirds of the company's board was replaced.

Southwest Airlines on Thursday said Executive Vice President and Chief Financial Officer Tammy Romo will retire from the role effective April 1, after more than three decades with the airline. The Dallas-based carrier said it will begin a search for Romo's replacement.

Southwest Airlines is ringing in the new year with one-way airfares as low as $49 on some routes. Deals are also available on cruise, rental car, hotel and vacation packages as part of the sale.
