Which line at airport security is the shortest?
It's often not the queue you're in, and it's usually not even the priority lanes set aside for 'premium' travellers in first or business class, or holding the appropriately shiny status card.
No, the fastest lane is almost always the one reserved for airline crew – and that's the path Cathay Pacific has tapped to give its top-tier frequent flyers a fast-track at Hong Kong.
It's a canny solution to the fact that Hong Kong International Airport has no priority lanes: all passengers are funnelled into the same, often-crowded channels for their security check, before proceeding to passport control.
But if you're a Diamond member of Cathay Pacific's Marco Polo Club rewards program, you can expect to receive this invitation to use the crew lane from the first class checkin area (that makes it worth dropping by even if you've checked in online).
With this 'courtesy channel' pass in hand, head to the counter at the far right of the Departures entrance just beyond the Cathay Pacific checkin desks (this is the Departures South zone).
You'll be waved through to the crew lane, and in no time at all you'll be zipping through passport control (especially if you have access to the automated e-channel gates) – after which comes the hardest decision of the day: which lounge to visit?
It's worth noting that this perk is exclusive to Marco Polo Club Diamond card-holders: it's not available to other Oneworld Emerald-grade members such as Qantas Platinum or BA Executive Club Gold.
