Palm Beach International Airport (PBI) is about to undergo one of the most unusual code changes in recent US aviation history. On August 18, 2026, the airport’s long-standing PBI IATA code will officially become DJT, reflecting the airport’s new name, President Donald J. Trump International Airport. While the change has generated political attention, travelers are far more likely to wonder what it means for booking flights, checking in, and navigating the airport.

For most passengers, the answer is reassuringly simple: very little will change beyond the three-letter airport code displayed on booking websites, boarding passes, and baggage tags. Airlines, airports, and global reservation systems have spent months preparing for the transition, ensuring that the switch from PBI to DJT happens without disrupting scheduled operations. The first flights using the new identifier are set to depart early on the morning of August 18.

From PBI To DJT: What Travelers Need To Know

Florida officially renamed Palm Beach International Airport to President Donald J. Trump International Airport on July 9 after legislation signed earlier this year by Governor Ron DeSantis. However, because IATA airport code changes require coordination across the global aviation industry, the familiar PBI identifier remained in use for several weeks before the scheduled mid-August transition.

Beginning August 18, passengers booking flights to or from West Palm Beach will see DJT instead of PBI in airline reservation systems. Airport officials have emphasized that this is strictly an identifier change rather than an operational one. The airport’s runways, terminals, security checkpoints, airlines, and flight schedules remain unchanged, meaning travelers should expect the same airport experience despite the new branding.

Why An Airport Code Change Takes Weeks And Will It Affect Flights?

Changing an airport’s IATA code is considerably more complicated than replacing signs outside the terminal. The three-letter identifiers are embedded throughout the aviation network, including airline booking engines, departure control systems, baggage handling networks, flight planning software, cargo documentation, loyalty programs, and airport databases used worldwide.

That is why airport officials separated the airport’s renaming from the code transition. While the airport officially adopted its new name in July, airlines continued using PBI until August 18, allowing reservation systems, distribution platforms, and travel agencies sufficient time to update millions of records before the code became active.

First Scheduled DJT Departures In The Morning Of August 18

The airport has 35 scheduled departures on the first day using the new DJT airport code. The first two departures are scheduled simultaneously at 6:00 AM, with an American Airlines flight to Charlotte Douglas International Airport(CLT) and a Delta Air Lines service to Hartsfield-Jackson Atlanta International Airport(ATL). Those flights will become the first commercial departures anywhere in the world to use the airport’s new DJT identifier.

Although the airport’s identifier is changing, its route network remains virtually identical. According to schedule data through December, Atlanta will remain the airport’s busiest destination, with 1,329 scheduled departures operated by Delta Air Lines. Newark follows with 1,055 United Airlines departures, while Charlotte ranks third with 649 American Airlines flights, underscoring the airport’s importance as a connecting point for several major carriers.

Other major destinations include New York-LaGuardia with a combined 800 departures operated by Delta and American, Dallas/Fort Worth with 459 flights, Philadelphia with 444, Washington National with 392, and Chicago O’Hare, where American and United together account for more than 550 departures. The schedule also includes service to Boston, Houston Intercontinental, Detroit, Washington Dulles, Denver, Los Angeles, Minneapolis-St. Paul, Marsh Harbour in the Bahamas, and Toronto in Canada, demonstrating that only the airport code is changing, while the rest remains unchanged.

For travelers, the biggest adjustment will simply be recognizing DJT when searching for flights or reviewing itineraries. Passengers who booked before August 18 may still see PBI on older confirmations, while newer bookings, boarding passes, baggage tags, and airport displays will show DJT. Airlines have coordinated the transition across their reservation systems to ensure a seamless changeover.

Airport renamings are relatively common. For instance, all three airports of Moscow changed their names in 2019 to include famous figures from Russian History, according to The Moscow Times. Italy also changed the name of its biggest Milan airport, Milan Malpensa Airport (MXP), to Milano Malpensa Silvio Berlusconi International Airport in 2024, though the new name didn’t stick, as many protested the idea of naming the airport after a controversial political figure, according to Il Post.

However, changing an IATA airport code is much rarer because of the extensive coordination required across global aviation. Some airports retain historical codes long after changing names, such as Orlando International Airport (MCO), while others receive entirely new identifiers when circumstances warrant it. The transition from PBI to DJT places West Palm Beach among the relatively small group of airports that have changed both their official name and their globally recognized airline code. The list includes New York International Airport (JFK), which used to be Idlewild Airport (IDL), and Chisinau International Airport (RMO), which used to be called Kishinev Airport (KIV) in the Soviet period.

Basically, the renaming is far more significant symbolically than operationally. The only noticeable difference that passengers will see is the new three-letter code DJT instead of PBI, which marks the beginning of a new chapter in the airport’s history.
