Asiana Airlines on Thursday resumed service from Incheon near Seoul to Hiroshima Airport, more than two weeks after one of its airliners skidded off the runway after a hard landing.

A flight from Incheon arrived at the airport Thursday evening, while the airline will restart service from Hiroshima to Incheon on Friday.

The April 14 accident left more than 20 passengers aboard Flight 162 from Incheon injured.

Asiana said it conducted pilot training and an emergency check of their skills following the accident. In May, staff overseeing piloting technique will also board flights to Hiroshima.

The airline will provide daily round trip flights between Incheon and Hiroshima through May 22 but reduce the number of flights per week to five from May 23 in expectation of falling demand due to the accident.
