When using an Octopus card, there's no charge for MTR trips when connecting to the airport express. Normally this would mean you wouldn't pay for the Admiralty<->Central leg when connecting to/from the airport express.

However it also applies if you catch the Airport Express at Tsing Yi. Thus you can ride the MTR from Admiralty to Tsing Yi (which requires a transfer at Lai King - but it's directly across the platform so a simple change), and then pick up the Airport Express from there.

Total charge on Octopus is HK$65, rather than the HK$110 via Central/Hong Kong station. Travel time was about 10 minutes more.

In practice I'm not sure I would have bothered - but the fact I had ended up with exactly $15.3 on my Octopus card ($65.3 including the $50 you can go negative!) was a sign that this was the route to take
