Major air cargo carriers said they have no immediate plans to add China flights to replace the capacity lost amid steep cuts to passenger travel due to the new coronavirus, as many factories have remained shut down after the Lunar New Year.

Aviation data firm OAG said there would be more than 25,000 fewer flights operated to, from and within China this week compared with two weeks ago, with 30 airlines halting services.

About half of the air cargo carried globally is in the belly of passenger jets rather than in dedicated freighters, and the flight cuts have made the Chinese market more dependent on freight haulers.
