WASHINGTON, Feb 19 (Reuters) - U.S. President Donald

Trump said on Wednesday his administration may have to go a

different route with the Air Force One planes, ratcheting up

pressure on Boeing ( BA ), which is at least three years behind

schedule in delivering two new Air Force One jets.

Trump and the White House have recently railed against the

jet manufacturer, saying Boeing ( BA ) has failed to deliver a new

plane on time.
