Check-in staff at departure airports have refused to allow regular visitors to South Korea to board flights to Seoul due to not having newly required paperwork, an oversight several blamed on poor efforts to publicize the requirement.

A dozen travelers told Korea Pro that they arrived at their airports unaware of the Korea Electronic Authorization (K-ETA) system, with ten denied boarding and two able to file a last-minute application. 

A Korea Proinvestigation found that as of last week many ROK foreign ministry websites still made no mention of the need to have K-ETA paperwork processed before departing for Incheon
