The cause of Wednesday's crack in one of the window's multiple panes was not immediately known.
Passengers scurried back away from the window, the cabin pressurisation held, and the Flight 967 diverted to Cleveland.
Airline consultant Robert Mann said windows are periodically polished to remove the formation of tiny cracks in the acrylic windows from exposure to chemicals and the sun's rays.
She wrote: "Window on plane cracked during flight".
The US Federal Aviation Administration will look into what caused the window to crack in the latest case. After being shuttled on another plane, passengers lauded the plane's crew for handling the situation smoothly.
Southwest said the aircraft landed uneventfully and maintained pressurization because each window has multiple layers. They estimated the sales drop cost the airline between $50 million and $100 million.
The National Transportation Security Board is investigating the engine failure and is still looking for debris from the engine.
