Within 24 hours, you go through the AE train turnstiles at Hong Kong Station. Is it smart enough to charge your Octopus just the difference in fare between Kowloon and Hong Kong trips to the airport? Or do you get away with not paying the extra fare? Or does it not link up your previous fare payment at Kowloon and charge you a full fare?
It will again charge you the full fare from Hong Kong Station, so I assume just adding 10 HKD will get you a red cross. Learned it the hard way myself. Can't say if there's any recouse if you approach the counter though before/after the charge, long line at the time and in a rush.
This was ~4 years ago and i have not made this mistake again (fortunately). Maybe the rules have changed, but at the time that stunt cost me 190 HKD
