When this route gets cheap.
The cheapest itinerary we are tracking flies Ryanair nonstop and takes about 2.5 hours outbound, on a 8-night trip. At $81 for 1,367 km each way, that works out to about $30 per 1,000 km flown. That is below the $41 per 1,000 km typical of short-haul fares here. Across the 8 departure cities we track at a similar distance from Porto, this fare ranks 5th — 53% above the $53 from Milan. That puts it in the cheaper half of the 15 routes of similar length we watch out of Dublin, where the middle fare is $106. We have 3 months 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.

These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
DUB → OPO, answered.
How far in advance should I book DUB → 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We do not publish a number for this, because we cannot measure it yet.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 Dublin to Porto?
Yes — the current board includes nonstop fares (Ryanair). The outbound leg runs around 2.5 hours.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). 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.
