Evidence suggests that the risk of transmission on board aircraft is low. For example, contact tracing for a flight from China to Canada with a symptomatic COVID-19 passenger revealed no onboard transmission and the same was true for a flight between China and the United States with 12 symptomatic COVID-19 passengers.
Mask-wearing by passengers and crew, however, will reduce the already low risk, while avoiding the dramatic cost increases to air travel that onboard social distancing measures would bring.

I pray God will make our living save.
