While Kim has taken a few flights to travel abroad, his father Kim Jong Il was reportedly afraid of air travel.

The journey to Russia’s Vladivostok is about 1,000 kilometres long and takes roughly one full day to complete on the armoured train. The North Korean leader last completed the journey in April 2019 to meet Russian President Vladimir Putin.
Kim Jong Un has also taken a train to China’s Beijing at least twice after taking control in 2011.
