American Airlines stock slips before open as Northeast blizzard snarls flights and shelf filing hits tape
American Airlines shares fell 4.8% to $12.93 in premarket trading after a Northeast blizzard forced widespread flight cancellations. The company also filed a shelf registration late Monday, allowing for possible future sales of stock or debt. Operations resumed at Washington Reagan National and Philadelphia, with New York and Boston expected later Tuesday. Delta and United stocks also declined.
