Palm Beach International Airport has officially been renamed President Donald J. Trump International Airport as of Thursday morning. Eric Trump, the president’s son, was on the first plane to touch down at the airport after the name change at 5:01 a.m.

The law, which was passed in March, was due to take effect July 9. The airport code will change from PBI to DJT in one month, after more than half a century of operating under the Palm Beach International name.

It is rare for airports to change their codes, but the International Air Transport Association said it had received a request to change the code from major airlines, including Delta, United, American Airlines, JetBlue and Southwest. 

“IATA has acted on a request from airlines serving Palm Beach International Airport to change the airport’s IATA 3-letter code from PBI to DJT, along with the change of the location name to President Donald J. Trump International Airport,” a spokesperson for IATA said. 

Eric Trump expressed his excitement over being the first to land at the airport under its new name on Fox News.

“There’s no way in hell I was letting UPS be the first plane to land,” he said. “So we got on Trump Force One … and then air traffic control comes on, and you know, welcome to Trump Force One. You’re the first plane to ever land, you know, at this airport.”

“And so we touched down at exactly 5:01 a.m. this morning, and it was a beautiful day,” he added. “I don’t think there’s anybody more synonymous with Palm Beach than Donald Trump, and maybe all of Florida.”
