Context: AirTran Airways was an American low-cost airline headquartered originally in Orlando, Florida, then in Dallas, Texas, after its acquisition by Southwest Airlines, into which it was integrated.  AirTran operated nearly 700 daily flights, primarily in the eastern and midwestern United States, with its principal hub at Hartsfield-Jackson Atlanta International Airport where it operated nearly 200 daily departures.  AirTran's fleet consisted of Boeing 717-200 aircraft, of which it was the world's largest operator, and Boeing 737-700 aircraft.  It was fully integrated into Southwest Airlines on December 28, 2014. Southwest Airlines Flight 812 (SWA812, WN812) was a passenger flight which suffered rapid depressurization at 34400 ft near Yuma, Arizona, leading to an emergency landing at Yuma International Airport, on April 1, 2011.  The incident caused minor injuries to two of the 123 aboard.  The aircraft involved, a Boeing 737–300, was operating Southwest Airlines' domestic scheduled service from Phoenix Sky Harbor International Airport, Phoenix, Arizona, to Sacramento International Airport, Sacramento, California.

On December 8, 2005, the airplane slid off a runway at Chicago-Midway while landing in a snowstorm and crashed into automobile traffic, killing six-year-old Joshua Woods.  This is the first, and so far, only accident involving Southwest Airlines to result in a fatality.  It is also the first accident involving the airline to result in the death of someone not on the plane itself.

It concerned the nature of Title III of Americans with Disabilities Act of 1990.  The court determined that Southwest Airlines website is not a “place of public accommodation” as defined in Title III of the Americans with Disabilities Act of 1990.  The case determined that the Southwest Airlines internet website was not in violation of the Americans with Disabilities Act of 1990 as Americans with Disabilities Act (ADA) concerned with a physical existence and hence cannot govern what it is in cyberspace.  Judge Seitz also explained that the “virtual ticket counter” Southwest Airlines Co’s website was a virtual construct and hence not a “public place of accommodation” and as such “To expand the ADA to cover "virtual" spaces would be to create new rights without well-defined standards".
