WASHINGTON (AP) — It’s no simple matter to move the commander in chief from point A to B, and it’s even more complicated when the president is seeking a second term.

President Joe Biden recently spent three days in Pennsylvania, a pivotal state in the 2024 campaign, and he plans to be in Virginia and Florida this coming week. The Democratic incumbent is seeking an edge over Republican Donald Trump as he ramps up his travels around the country.

Here’s a look at how much it costs and who pays the bill during the campaign season.

HOW MUCH DOES IT COST?

It’s not cheap to fly the president’s fleet.

The White House uses Sikorsky helicopters known as Marine One when the president is aboard, as well as custom Boeing 747s that are immediately recognizable as the iconic humpback Air Force One. (Sometimes the president uses a more modest modified 757 if his destination is nearby or if a runway isn’t long enough to accommodate the bigger plane.)
