I have already booked a ticket from Beijing to Chicago for September by paying cash. Recently there’s rumor about the potential increase in the number of direct flights between China and US along with the remediation of political relationship between the two counties. Just in case I would like to cancel the ANA ticket, do you know how much it would cost for any voluntary cancellation? I know it cost 3000 miles for award ticket cancelation, but how about if it is a paid ticket? Does the cost varies depending on how many days left before departure? Thx
