WASHINGTON (AP) — An airline-industry trade group predicts that passenger traffic over the Thanksgiving holiday will drop 4 percent from last year.

The Air Transport Association made the forecast Monday, despite deep discounting by airlines over the past several months.

"It is increasingly apparent that the economic head winds facing the airlines and their customers are anything but behind us," said James C. May, the group's president and chief executive officer. He said the unemployment rate jumping above 10 percent last month has affected consumer buying decisions.

With fewer flights, planes are likely to be full over Thanksgiving, the trade group said.
