New security measures take effect this week for all commercial airline flights to the United States from other countries.
The new measures were put in place to avoid a ban on laptops and other large electronic devices in the cabin.
"They're doing much more thorough screening of the electronics, of everything being brought on board, all the carry on pieces, even the checked luggage," said Steve Cosgrove, of Dynamic Travel & Cruises.
Changes will include enhanced screening of passengers and electronic devices, along with stricter security standards for aircraft and airports.
Passengers bound for the U.S. will have to answer a lot more questions from security officers looking for anyone posing a threat.
"Those questions vary by what red flags might be raised because of where you were before this flight, where did you come from before you got to this one, how long have you been here, your traffic pattern in the past," Cosgrove said.
"They're not going to tell us what's going to raise the red flags, but everybody has a different situation," Cosgrove added.

The latest news from around North Texas.
The new measures affect every flight to the U.S. from another country — that's about 2,100 flights a day and 325,000 passengers.
The stricter measures have to be in place by Thursday, and most airlines have already complied.
The new measures were announced four months ago after the federal government tried a ban on laptops and other devices from airports in 10 Muslim-majority countries.
