I toured a Boeing Business Jet, an airline-sized private plane equipped like an apartment, and was shocked at just how spacious it was

Boeing has a fleet of airline-sized private jets which have been running off the production line for over 20 years.

Boeing Business Jets are designed to appeal to high net worth individuals who want larger, more comfortable private planes.

I toured one of the BBJ models which belongs to a well-known author and motivational speaker.

The plane is around 80-feet long and can comfortably hold 19 passengers.

Inside the main cabin, the first compartment featured a large open-plan seating area, composed of reclining seat pairs, dining tables, and sofas.

The dining table sat in front of a large entertainment screen and was set when I visited.

The large chairs also had fold-out tables and side storage compartments ...

… and featured control buttons for music.

A larger table with sofa chairs on each side was situated in the next compartment. The space was slightly smaller and more private, which made me think it could perhaps be used for conferences or meetings.

A master suite was situated further down the plane, replete with a comfy-looking double bed.

The bedroom also featured its own entertainment screen mounted on the wall.

An en-suite bathroom with floor to ceiling mirrors was situated next door.

The en-suite also had a large vanity unit with panel lighting and high-end toiletries.

Back at the front of the plane, a kitchen and crew rest were situated off the entryway.

The crew rest had two large reclining armchairs.

A spacious kitchen was located at the front of the plane close to the cockpit.

It came complete with Nespresso coffee machines and a milk frother.

The main bathroom with a large sink and vanity unit was also situated at the front of the plane.

The model I toured — the BBJ1 — is part of a previous generation of Boeing Business Jets. The original BBJ model is based on Boeing's 737-700 commercial airline and first rolled off the production line in July 1998.

Newer models which have since joined Boeing's business jet fleet include the Boeing Max family, the BBJ 787-8 and BBJ 787-9 Dreamliners, as well as the BBJ 747-8, the world's largest private jet.
