LANTANA, FLA. — President Donald Trump wants small businesses to thrive, but his frequent Mar-a-Lago visits have flight schools and other companies at a nearby airport in a financial nosedive.



The Secret Service closed Lantana Airport on Friday for the third straight weekend because of the president's return to his Palm Beach resort, meaning its maintenance companies, a banner-flying business and another two dozen businesses are also shuttered, costing them thousands of dollars at the year's busiest time. The banner-flying company says it has lost more than $40,000 in contracts already.



The airport, which handles only small, propeller-driven planes and helicopters, is about 6 miles southwest of Mar-a-Lago, well within the 10-mile circle around the resort that's closed to most private planes when he's in town. Trump flies into Palm Beach International Airport, which is 2.5 miles from Mar-a-Lago, and remains opens as it handles commercial flights.



The Lantana owners are pushing compromises they say will ensure Trump's security while keeping their businesses open. They involve letting pilots fly in a closely monitored corridor headed away from the resort until they are outside a 10-mile ban around Mar-a-Lago and a 30-mile zone where flying lessons are restricted. Pilots, planes and cargo would undergo preflight screening by Transportation Security Administration agents.



"None of us are suggesting that we shouldn't do everything to keep the president safe but we believe there are things that can be done to keep us in operation," said Jonathan Miller, the contractor who operates the Palm Beach County-owned airport.



The airport and its 28 businesses have an economic impact of about $27 million annually and employ about 200 people full-time, many of them making about $30,000 a year. They don't get paid when the airport is closed.



Miller is already losing a helicopter company, which is moving rather than deal with the closures. That will cost him $440,000 in annual rent and fuel sales.



White House spokeswoman Stephanie Grisham directed questions to the Secret Service. The agency also declined comment. Flight restrictions have long been standard around buildings where a president is staying to protect him from an airborne attack.



U.S. Rep. Lois Frankel, a Democrat who represents the area, met with the business owners this week. She said she will meet with the Secret Service next week to see if a compromise can be reached.



Lantana Airport opened in 1941 as a Civil Air Patrol station, with planes flying along the coast during World War II to spot German submarines attempting to sink cargo ships. Today, the 300-acre, three-runway facility handles an average of 350 arrivals and departures daily, peaking on winter weekends as tourists enjoy South Florida's temperate weather. Summer, with its stifling, visitor-repelling heat and the constant threat of plane-grounding thunderstorms, is not nearly as lucrative.



Marian Smith, owner of Palm Beach Flight Training, said her 19-year-old business is losing 24 flights daily when closed and three students cancelled. She lost $28,000 combined the last two weekends and will lose $18,000 on this President's Day weekend. She estimates her 19 instructors are each losing up to $750 a weekend.



"What's frustrating is that we get little notice when this is going to happen," she said.



This week, rumors began Monday. The closure notice arrived Wednesday.



David Johnson, owner of Palm Beach Aircraft Services, said his 27-year-old repair and maintenance business generates $2 million in sales annually, but has taken a hit over the last month and he fears it will cascade if flight schools like Smith's close. He has written a letter he hopes gets delivered to Trump this weekend asking him, one businessman to another, to help resolve the conflict.



"Even if the TSA had to screen every pilot going out of here, we would be open to that," Johnson said. "But so far, we've gotten nothing."



Jorge Gonzalez, owner of SkyWords Advertising, a banner towing service, said his company lost four contracts totaling $42,500 because of Trump's visits. He wants exceptions made for three pilots to fly within the restricted zone when the president visits because it is where thousands of residents live and tourists stay.



"We have spent 10 years building this business," said Gonzalez's wife, Hadley Doyle-Gonzalez. "We just can't pick up and move."
