When this route gets cheap.
The cheapest itinerary we are tracking flies Air Transat nonstop and takes about 7.5 hours outbound, on a 14-night trip. At $549 for 5,239 km each way, that works out to about $52 per 1,000 km flown. That is above the $43 per 1,000 km typical of medium-haul fares here. Across the 18 departure cities we track at a similar distance from Montreal, this fare ranks 5th — 56% above the $353 from Los Angeles. That puts it in the cheaper half of the 11 routes of similar length we watch out of Lisbon, where the middle fare is $549. We have 2 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 Montreal: Jun–Sep.

The median cached fare across this calendar is 17% higher than when tracking began on 8 Aug — $507 then versus $591 now, across 9 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $507, on 16 Sep.
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
LIS → YUL, answered.
How far in advance should I book LIS → Montreal?
We do not publish a number for this, because we cannot measure it yet.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 Lisbon to Montreal?
Yes — the current board includes nonstop fares (Air Transat). The outbound leg runs around 7.5 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.
