Most journalists travelling with the US president don't see much of the interior of Air Force One, the presidential jet.

The press cabin is in the back of the plane, accessible by a rear set of steps and a quick turn of a corner.

To reach the presidential suite at the front of the plane would require negotiating with the armed Secret Service agents in the next-door cabin.

On Donald Trump's trip to the Middle East this week, when the future of the famous plane was a huge talking point, Fox News host Sean Hannity had priority seating and access to the president to conduct an in-flight interview.

But the rest of us in the travelling press pool were consigned to our small section of the plane.

It was a whirlwind trip, hitting three nations in three nights, half a world away. The president described it as an "endurance test" - one that his staff and those of us in the press pool had to manage, as well.

The presidential jet is not a bad way to fly, however. The 14 seats are comfortable, roughly on par with a first-class domestic flight.

There's a bathroom and a table with snacks (including the coveted Air Force One-branded M&Ms bearing the president's signature, which aren't available anywhere else).

The cabin has a pair of television monitors - usually tuned to the president's preferred cable news channel (CNN during Joe Biden's term; Fox News for Trump). On occasion, they've been set to a football game or other sporting events.

For longer flights, the on-board kitchen serves plated meals (the president eats from a different, fancier menu). On short hops, there's usually food in a takeaway bag.

But the interior of this famous aircraft could soon undergo a radical refit if, as looks likely, Trump accepts the Qatari offer to supply a new "palace in the sky" - the biggest foreign gift ever received by a US president.

Technically, "Air Force One" is a radio call sign,........
