Palm Beach International Airport received its new name as President Donald J. Trump International Airport on Thursday. While signs are being updated, the well-known airport code used by travelers will remain unchanged for another month.

Florida Governor Ron DeSantis approved legislation in March to rename the airport in honor of President Trump. The Federal Aviation Administration confirmed the name switch would begin July 9.

The three-letter code seen most often by passengers, currently PBI, will stay active until August 18 when it becomes DJT.

This creates a 40-day period where the FAA location identifier and International Civil Aviation Organization code used by pilots and air traffic controllers will be DJT, while passengers continue booking with PBI.

Airline analyst Henry Harteveldt of Atmosphere Research Group noted that carriers added hard coding to reservation and baggage systems to route passengers and luggage correctly during the transition.

Airlines indicated that searches using the PBI code will initially point to flights at the newly named DJT airport. Flight attendants may also have flexibility to greet arrivals as landing in West Palm Beach rather than using the full new name.

Changes to airport codes by the International Air Transport Association are uncommon and usually require strong justification tied to safety concerns.

The request to update the code originated from major U.S. carriers serving the airport, including Delta, United, American, JetBlue and Southwest.

An IATA spokesperson confirmed the organization approved the shift from PBI to DJT alongside the name change, with the new code taking effect August 18 to allow full system updates.

The airport website advises travelers to keep using PBI until the August switch occurs.

The facility states it remains focused on serving all passengers and delivering a smooth travel experience during the adjustment.

Nearly eight million passengers pass through the airport each year. President Trump frequently arrives there en route to his Mar-a-Lago resort.

In May, Palm Beach County commissioners approved a licensing agreement allowing the Trump name at the airport after the Trump Organization sought trademark protection for the name at airports nationwide.

The deal bars Mr. Trump from receiving any royalties or fees from merchandise sales, though the airport may use his name and likeness in promotions.

Twelve airports nationwide currently carry presidential names.
