PORTLAND Planes circled around Portland International Airport Thursday as heavy air traffic waited to land on one of the busiest travel days of the year.

Heavy fog in Seattle caused several flights to be diverted to Portland making for even more flights landing than expected, according to a spokesperson with the Port of Portland.

A few cargo flights landed at PDX to wait for the fog to clear in Seattle while a flight from Tokyo and an Asiana flight also landed at the airport.

KGW received several calls and emails from curious viewers who saw the sky filled with planes and swirling contrails above Northeast Portland.

As many as 50,000 people are expected to fly out of PDX for the Thanksgiving holiday weekend.

On Wednesday morning only three flights had been delayed and only by 30 minutes.

Travelers were getting to the airport with plenty of time to spare, some three or four hours ahead of their flights Wednesday.

In Portland, traffic problems started early on Wednesday with metro roads clogging to a stand still, though Portland International Airport remained fairly calm through the afternoon.
