(AP) - Some small private airports in New Jersey say the flight restrictions that accompany President Donald Trump's visits to his Bedminster golf club are putting a damper on their business.

Visits from the president trigger a ban on all air traffic within 10 miles of Trump National Golf Club and restrictions on traffic within 30 miles. Restrictions are in place this weekend.

That creates problems for airports as far away as Hunterdon County and Bucks County in Pennsylvania. It restricts training flights, forcing pilots to fly with tracking devices and grounding skydivers and hot air balloons.

Solberg Airport co-owner Suzanne Nagle told MyCentralJersey.com the economic impact could be "devastating."
