When this route gets cheap.
The cheapest itinerary we are tracking makes 2 stops and takes about 17.5 hours outbound, on a 2-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $852 for 10,821 km each way, that works out to about $39 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 9 departure cities we track at a similar distance from Porto, this fare ranks 6th — 33% above the $639 from Bangkok. For context, the middle fare among the 35 routes of similar length we watch out of Hong Kong is $830. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Porto: May–Jun · Sep–Oct.
We are still collecting this route's months — 1 month of cached prices so far, too few to chart.

Good to know
HKG → OPO, answered.
How far in advance should I book HKG → Porto?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Hong Kong to Porto?
The current cheapest fares involve a connection, ticketed under Air China. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 18 September). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
