U.S. carriers have begun reporting April traffic figures, and though the numbers are generally down, some analysts say there are signs of a pending recovery. At Continental Airlines, traffic was off 3.8% in April, much better than the 9.7% drop reported in May. American Airlines also saw smaller declines, with a 4.7% slide in April compared to 10.9% in March. Meanwhile, at AirTran Airways, traffic fell only 0.3% for the month. All three airlines said their planes flew fuller in March, boosting hopes for increased pricing power in the busy summer months.
