While some things may evolve over time, our core focus remains the same: providing a safe, reliable, and welcoming airport experience."Palm Beach's travel hub isn't the only airport undergoing changes during Trump's presidency.On July 29, Trump unveiled his plan for a $22.5 billion renovation at Washington Dulles International Airport in Washington, DC, adding or renovating more than 5 million square feet and eliminating the airport's "people mover" shuttles, among other upgrades.Take a look at the newly renamed President Donald J.
