The end of the holiday weekend brought one more reason for holiday commuters to be thankful: Traveling home early Sunday appeared to go as smoothly as an electric knife through the turkey.

So said officials at Bay Area airports and for the California Highway Patrol, after an early afternoon that saw flights depart on time and bumber-to-bumper traffic jams avoided.

"Nothing terribly out of the ordinary," CHP Officer James Evans said of traffic on the Bay Area highways. "Hopefully, it stays that way."

Through 6 p.m., nearly all planes were running on time at San Francisco International, Oakland International and Norman Mineta International airports. Those flights were expected to remain on time throughout the night, authorities said, because of mostly calm weather throughout the nation.

"It's pretty mellow around the country," National Weather Service forecaster Steve Anderson said. "The only snow is in northern Idaho and Montana, and the only rain is in Portland, Ore., and Seattle. Calm everywhere else."

The Sunday after Thanksgiving is one of the busiest travel days of the year, and is usually marked by long lines at airports that only get longer when delays occur elsewhere. But spokesmen in San Francisco and Oakland said lines at their airports were not much longer than any other busy travel days.

"We ran into a lot of good luck with the weather systems, because we do have a heavy customer volume," said Chuck Navigante, the duty manager at SFO. "It's been smooth."

Navigante said 130,000 people were expected to pass through SFO on Sunday. About 35,000 were expected to depart or arrive in Oakland. Numbers for Norman Mineta airport in San Jose were not available immediately.
