BOSTON (AP) _ Boston Marathon bombing survivor and professional dancer Adrianne Haslet-Davis took to Twitter to voice her frustrations with America Airlines for losing her luggage _ including her prosthetic leg.

She tweeted on Thursday night: ``u lost my luggage w over $250k of leg & dance parts.''

Haslet-Davis lost her lower left leg in the April 2013 marathon attacks. She was able to dance again publicly at a March 2014 TED Conference in British Columbia, Canada thanks to a prosthesis made for her at the MIT Media Lab.

Spokesman Joshua Freed says the airline is ``terribly sorry'' for losing the bag and is working to get it back to Haslet-Davis as soon as possible.

Haslet-Davis couldn't be reached for comment.
