As an estimated 50 million American drivers and 3.5 million flyers are traveling this Thanksgiving, the president insisted officials were doing everything they can to prevent a terrorist attack.

"Right now, we know of no specific and credible intelligence indicating a plot on the homeland," President Obama said during a briefing.

Jeff Cofini and his children are traveling to Westchester from Tampa International Airport.

Terrorist attacks on public places in France and Mali, and ISIS claims that more are coming, have unnerved him.

"We actually had the opportunity to go to the Macy's Thanksgiving Day Parade in New York City, and we turned it down," he said. "It's not worth the risk."

The President asked travelers to report anything suspicious, as police dug in around Times Square and stepped up security at airports nationwide.

"Our counter-terrorism and intelligence, homeland security and law enforcement professionals at every level are working overtime," President Obama said.

The president's statements come a day after the State Department issued a travel warning that said, "ISIS and al-Qaeda are planning attacks in multiple regions, using conventional and non-conventional weapons and targeting official and private interests."

Traveler Jacky Seal says she doesn't sweat it.  "There is nothing I can do about it. I am just hoping that things are secure."

Many others said they were pressing ahead with plans.  Meghan Gabb is headed to the Big Apple with her daughter.

"If we just stop our life, than what kind of life are you living?" said Gabb.

Officials at TIA expect an eight percent increase in traffic from last year's Thanksgiving holidaya.

They recommend you arrive 90 minutes before your flight.
