Air-travel delays easing
Commercial air traffic began returning to normal across the U.S. Sunday as the Federal Aviation Administration ended the furloughs of air-traffic controllers that had led to thousands of flight delays and cancellations over the previous week. There were 1,867 delayed flights and 41 cancellations as of late Sunday afternoon, less than the first day of furloughs the previous Sunday, and below the 30-day average, according to airline data tracker FlightStats. Delays on Saturday also returned to pre-furlough levels, according to FlightStats.

"I think it's no surprise then that the iPhone 5 is selling worse than expected," said Brian Colello, an analyst at Morningstar.
McDonald's considers all-day breakfast, delivery
