American Airlines 'Sorry' for Losing Boston Marathon Bombing Survivor's Prosthetic Leg

"Her bag has been located," American Airlines said.

Haslet-Davis, a professional dancer, lost her leg in the explosions near the finish line of the Boston Marathon in 2013. She tweeted Thursday evening that the airline lost a bag containing her prosthetic leg and dance parts, valued at over $250,000.

Haslet-Davis asked American Airlines to please respond, which it did, first tweeting, "We're doing all possible to get you and your bag back together again."

The company followed up overnight with a statement: "We're sorry this happened. Her bag has been located and we will reunite her with it as soon as possible."

Haslet-Davis’ original tweet had been shared by over 100 people, many of whom slammed American Airlines while also calling on news media to publicize Haslet-Davis’ story.

Haslet-Davis had shared a positive note with those who have followed her story and have tried to help.
