U.S. President Donald Trump has voiced his dissatisfaction with Boeing for failing to fulfill its obligations under the contract to construct two new Air Force One aircraft on time.

Trump said that Boeing’s production of the two Air Force One planes is behind schedule.

Speaking from one of the presidential aircraft in service at the moment, Trump added that he is searching for other options because of Boeing’s hold-up.

“No, I’m not happy with Boeing,” Trump stated. We awarded that contract to Air Force One a long time ago, but they take a long time to complete it.

“We might get or purchase a plane, or something.”

Trump responded, “No, I would not consider Airbus over Boeing, but I could buy one that was used and convert it,” when asked if he would consider purchasing from Airbus, Boeing’s rival.

During Trump’s first term in office, the deal for two upgraded versions of the presidential plane—based on the contemporary Boeing 747-8—was negotiated.

Trump visited a 13-year-old Boeing 747-800 parked at Palm Beach International Airport a few days ago. The aircraft had belonged to the Qatari royal family.

Boeing has delayed the delivery of its new aircraft, which was originally scheduled for 2024, to 2027 or 2028.
