I had this issue earlier.. I noticed Poweramp unlocker runs in background.. If I force stop it, this problem occurs in airplane mode.. then I whitelisted the unlocker and verified again using data.. this solved licence check problem.. Still now It never asked for licence in airplane mode..
Why does Poweramp need to verify license through Google Play when Poweramp Unlocker is installed?
