 The number of airline flights canceled in the U.S. today has now exceeded 1,200, according to FlightAware.com. As airlines struggle to recover from Friday's technical glitch, Delta Airlines appears to be having the hardest time with more than half of the cancellations on the board so far. American Airlines and its flight attendants have reached a deal. American says the company and the Association of Professional Flight Attendants have agreed to a new contract that will give flight attendants better compensation and improved work rules.
