Trump says he could fly on Qatar's Boeing 747 converted for presidential use by February, while the Air Force estimates hundreds of millions on retrofits.

President Donald Trump said he could start flying in the new luxury jumbo jet as soon as February of next year.

The free Air Force One from Qatar, which Trump has described as a gift, has raised eyebrows after a $934 million transfer of funds was made to an unnamed classified project from the Pentagon, with officials in the Air Force saying that millions of dollars were needed to pay for renovating the aircraft.
