The move is effective 1 June and will restore services on 19 international routes, with 91 flights each week. Nearly 94pc of Korean Air's 900 weekly flights on 110 overseas routes are currently suspended. The first batch of restarts will lower that ratio to 84pc, as Korean Air will have 146 flights scheduled weekly on 32 overseas routes.
Routes that are reopening include Beijing, Frankfurt, Toronto, Washington and Seattle.
The flight restarts offer a glimmer of hope for Asia-Pacific refiners that have been battered by a plunge in jet fuel demand since route suspensions began in February. But Korean Air is not betting on a quick recovery. The airline has implemented a paid-leave programme that will sideline 70pc of its employees for the next six months. South Korea's largest refiner, SK Innovation, this week said it has minimised jet fuel output and is blending the product with low-sulphur fuel oil to help cope with the crisis.
