China overflight charge

[averagebusdriver]

Hello All,

I am hoping to get some clarity about a charge we had for a China overflight permit from Tong Da Air Service.

Although we requested a permit to operate within China, the flight was cancelled and we were charged an en route fee.

Is this normal, or did our handler make a mistake and forget to cancel the flight?


Thanks in advance for any comments and help.
