Korean Air will resume first class service after two years of suspension, in a bid to increase profitability amid surging demand for international flights.

Starting with the route to Washington on Sept. 1, first class seats will be available on flights to Paris from Oct. 1, to London, Atlanta and San Francisco from Nov. 1, and to Frankfurt next year, the airline said Tuesday.

The airline stopped operating first class cabins on all routes except flights to New York and Los Angeles in June 2020, as the coronavirus pandemic brought the airline business around the world to a near-complete halt.
