”I can't go home because they're sold out”... 1.48 million holiday train tickets left ”empty” in 5 years = South Korea

Over the past five years, four out of 10 tickets issued for KTX and other trains operated by Korea Railroad Corporation (KORAIL) during the Lunar New Year and mid-autumn festival holidays have been issued.
It was later discovered that the flight had been "cancelled." According to documents obtained from KORAIL by Tae Yeon, a member of the Land, Infrastructure and Transport Committee of the National Assembly of Korea, the flight was scheduled to run from 2020 to 2022.
A total of 33,334,107 tickets were issued during the 10th National Holiday period in 2014. Of these, 43.3%, or 15,230,000 tickets, were cancelled by buyers and KOR
AIL refunded the tickets. The cancellation rates for Lunar New Year and mid-autumn celebration were 42.6% and 43.9%, respectively. KORAIL resold the cancelled tickets, but only 4.5% of them were cancelled.
The proportion of cancelled tickets has been increasing over the last few years.
For this reason, KORAIL will be offering a 2020 refund policy for tickets starting from this holiday in order to provide as many seats as possible during the holiday period.
Rep. Yeom said, "We will strictly enforce measures to prevent cancellations, such as imposing sanctions on those who cancel tickets habitually, and we will increase the penalty fee during holiday periods and, if necessary,
"We need to ensure that people who need to travel can use the trains," he said.
