Among the nation's biggest carriers, American Airlines has the worst record for losing and mishandling luggage.
In the first nine months of 2015, the Forth Worth-based carrier lost or mishandled 4.04 bags for every 1,000 passengers, compared with an average rate of 3.31 lost or mishandled bags for the country's top 13 biggest airlines, according to the U.S. Department of Transportation.
But when American Airlines lost the luggage of Adrianne Haslet-Davis, it became big news. Haslet-Davis is a dancer who lost a leg during the Boston Marathon bombing. The misplaced luggage contained a prosthetic leg and other parts she uses to dance, valued at $250,000.
