"World's Worst Airline" 
North Korea Flies World’s Worst Airline to Beijing for First Time Since 2020

(Bloomberg) -- North Korea’s state airline made its first international trip since the start of the Covid pandemic, in a sign of easing border restrictions that could repatriate its stranded nationals abroad and increase trade with its powerful neighbor.
Flight data indicates than an Air Koryo passenger jet flew from Pyongyang to Beijing on Tuesday, which would be the first such commercial flight in more than three years. China’s Foreign Ministry said this week the country had given permission for the flight. Air Koryo is also set to operate flights on Friday and Aug. 28 between Vladivostok and Pyongyang, according to NK News, a specialist service on North Korea.
North Korean leader Kim Jong Un sealed the border at the start of the pandemic in early 2020. The move slammed the brakes on the little legal trade conducted by his heavily sanctioned state and also left stranded North Korea’s diplomats and thousands of workers sent to places such as Russia and China to earn hard currency for Kim’s regime.
In a sign of opening, North Korea last month allowed in high-level delegations from Russia and China for the first time since the start of the pandemic, and this month sent a group of its taekwondo athletes abroad to take part in a championship in Kazakhstan.
Signs of a resumption of trade with China, historically Pyongyang’s biggest partner, led Fitch Solutions to estimate North Korea’s economy returned to growth after two full years of contraction. Still, it added that significant uncertainties still remain.
Air Koryo has previously been ranked among the worst airlines in the world.

For those of you who are curious: they've had only one fatal crash in their almost 70 years of operations.. Their fleet is exclusively Soviet/Russian/Ukranian made, which explains why they've been able to keep up with maintenance despite the embargo.
Here's a review from a western traveler. The experience sounds pretty much like any government operated airline from a poorer country.
I don't trust anyone claiming "World's Worst" in a world where Frontier exists.
Air Koryo is the worst at generating profit for it's owners and misery for it's passengers.
