NBC NATIONAL NEWS — Good weather is being credited with helping provide a smooth ride for the estimated 39 million Americans driving to Thanksgiving this year.
Except for a soggy Pacific Northwest, it's sunny and dry most everywhere, which is also helping air travel.
"Flight schedules have been pretty much on time. The weather's been cooperating and the TSA has not enacted any new rules this year. So, if you've traveled in the past 12 months, you pretty much know what to expect when going through those security lines," says Orbitz air traffic analyst Chris Hills.
The TSA's relaxing of the rule involving shoes is cutting congestion, too.
Children 12 and under and seniors 75 and older don't have to remove their shoes when going through security.
Still, expect big crowds and long lines.
Train travel is easier, too.
Amtrak has every rail car in its fleet in service to carry what may be a record number of riders.
