China's Okay Airways resumed flights over the weekend after the Civil Aviation Administration of China (CAAC) gave it approval to re-start passenger operations last Friday.
The Boeing 737-800 carrying 62 passengers took off from Tianjin Binhai International Airport and landed at Harbin Taiping International Airport on Saturday morning.
The carrier plans to have six other domestic flights from Tianjin, its base in northern China, to other cities including Kunming, Sanya, and Chengdu this week, according to media reports. From 1 February, the airline says that it will be able to reinstate all its previously operated passenger services.
Okay voluntarily grounded its passenger operations early in December as a result of a dispute between its parent company, Juneyao Group, and its founder, former majority owner Liu Jieyin.
It applied earlier this month for CAAC approval to resume passenger operations on 21 January but state-run media reports say the regulator rejected its application, citing a need for more information.
