The private jet industry is big business at Palm Beach International Airport.
Like many others, they can take a hit when President Trump visits his Winter White House.
Suran Wijayawardana with Alerion Aviation says he can only operate between 8 a.m. and 5 p.m. with required pre-screenings when Trump is in town.
He says 20 percent to 30 percent of their business is after 5 p.m.
"Selling fuel is limited," said Wijayawardana.
The good news is businesses and the U.S. Secret Service now know what to expect so they can have a better plan in place.
"We've had to make accommodations as a business by mitigating operating hours and mitigating the impact on our clients," said Wijayawardana.
Suran is also the chairman of the National Air Transport Association. He's working to keep pre-screenings until 10 p.m. when the president in town.
"Do a little bit more business and it would help fuel companies and maintenance companies," said Wijayawardana.
He plans to have those discussions with Secret Service soon.
