The lines are gone at Denver's airport and a spokesman says he can't imagine too many stranded travelers are still there.

Hundreds of packed flights left the airport yesterday, full of passengers who had been stranded when a blizzard shut down the runways for almost two days last week.

At the height of the closure, it's estimated that 47-hundred travelers were camped out in the terminals.

The airport's two biggest carriers, United and Frontier, said they had a full schedule of flights Saturday and Sunday, including a dozen extra flights by United.

Neither the airlines nor the airport had a passenger count. But last Christmas Eve, an estimated 129-thousand passengers passed through Denver, the nation's fifth-busiest airport.
