Boeing has not officially confirmed any changes to the $3.9 billion fixed-price contract it signed during Trump’s first term. It has absorbed more than $2.5 billion in losses on the project.

Trump’s first extended overseas trip of his second term will see him talking to leaders of Saudi Arabia, Qatar and the United Arab Emirates.

Boeing has been working on Boeing 747-8s to become the new presidential planes to address "capability gaps" in the old fleet.
