Trump said he did not know the cost of Qatar donating and refurbishing a plane into "Air Force One": The Air Force would spend a lot of money.

Trump told reporters on Air Force One flying back from Scotland to Washington that he would "board this plane earlier" compared to other presidential planes being built by Boeing. "It's not a regular 747. It has a lot of things that other planes don't have, but we will get this plane a year and a half to two years ahead of schedule," Trump said.
