Assuming no other flights beat SpaceX to its goal and the person aboard isn't a repeat flyer (which has happened only once), the individual aboard SpaceX's first private flight will be the eighth-ever space tourist to leave the Earth's exosphere.
SpaceX has stated that the BFR would be capable of sending crews to the Moon and Mars.
No details have been revealed about who the passenger is and why they're flying, but SpaceX said it would reveal all on Monday.
At that time, SpaceX said two people signed a deal with SpaceX to make a trip around the moon aboard a Falcon Heavy rocket.
"No one has visited since the last Apollo mission in 1972". It's anybody's guess, but Musk did reply to a tweet with a Japanese flag emoji, prompting speculation that the tourist is from Japan. However the passengers were never named and the flight has yet to materialize.
The 31-engine BFR is part of the company's grand plan for travelling between planets, and will replace its current suite of rockets like the Falcon 9 and Falcon Heavy.
In December 2017, US President Donald Trump also issued a directive to "lead an innovative space exploration programme to send American astronauts back to the moon, and eventually Mars". Its design was first presented almost a year ago, and the concept boasted a single system that included a booster and a ship that could travel to the moon and Mars.
