Southwest has been sued by a search engine that the airline says breached its terms by displaying cheap flights Summary List Placement Skiplagged, a flight-information website, asked a New York court to rule on whether it was breaking Southwest Airline''s terms of service by posting flight airfares. "Skiplagged does not access Southwest.com or use the Southwest API to obtain data published on Skiplagged.com," the tech company said in its complaint, "and is not bound by the Southwest terms and conditions." The filing was curious in that Southwest hadn''t publicly accused Skiplagged of breaking its terms and services. The filing was instead an indirect response to another lawsuit where Southwest was suing a different online travel agency, although Skiplagged wasn''t named as a defendant. Since January, Southwest has been in a legal battle with Kiwi.com in federal court in Texas. Southwest in that lawsuit sought an injunction to stop Kiwi.com from displaying its flights. The airline has stated that it doesn''t allow online travel agencies to sell its flights without written permission. "Kiwi knowingly and intentionally targets the Southwest website to harvest Southwest''s fare and pricing information for its own commercial benefit and without Southwest''s authorization," the airline said in its complaint.
