The airport renaming was signed into law by Florida's Republican governor, Ron DeSantis.

"I don't think there's anybody more synonymous with Palm Beach than Donald Trump and maybe all of Florida," Eric Trump said.

He pointed out that the main road leading out of the airport is already called "President Donald J. Trump Boulevard."

And now anyone flying into Palm Beach will have a ticket where "you're going to see 'DJT' in perpetuity."

Travelers at the airport yesterday morning were mixed on the name change.

Corporate pilot Chris Bailey welcomed the switch, telling AFP that Trump has "certainly done enough to warrant a name of an airport."

But others were hostile.

"Palm Beach is a better brand. People don't really like Donald Trump," John Manov, a doctor, said. "It seems in poor taste."

Banknotes, buildings, bridge

Breaking the long-held US tradition against celebrating living figures -- and particularly serving presidents -- on currency and buildings, the Trump name and image are spreading rapidly.

Officials, including US Treasury Secretary Scott Bessent, were due to unveil the Donald J. Trump Bridge in Tennessee yesterday.

Washington already features the renamed Donald J. Trump United States Institute of Peace and giant posters with his face have been hung from the facades of major government buildings.
