Kenlie Tiggeman, the overweight passenger who garnered national attention last May after she claimed a Southwest gate agent told her she was "too fat to fly," is now suing the airline.

Tiggeman, who lives in New Orleans and blogs about weight loss on her website, AllTheWeigh.com, filed an injunction against Southwest in district court on April 20, alleging that the Southwest agents "did not follow their company policy and chose to discriminate, humiliate and embarrass" her in front of "airport onlookers," and that the airline uses "discriminatory actions ... toward obese customers."
