✈️ Flight Guide: Montreal (YUL) → Lisbon (LIS)

October in Portugal is prime for wine harvest experiences — the Douro Valley and Alentejo regions are active with vindima (grape harvest) tours, tastings, and winery open days. In Lisbon, look for seasonal food and wine festivals, cultural nights, and smaller-scale concerts and exhibitions as the city transitions to autumn programming. Coastal towns like Cascais and Setúbal host seafood fairs and market events in fall, while Sintra’s palaces remain a year-round draw with fewer crowds in October. Always check local event calendars for exact dates and book popular winery tours in advance to secure October slots.

October is generally an excellent time to fly from Montréal-Pierre Elliott Trudeau International Airport (YUL) to Humberto Delgado Airport (LIS): cooler, comfortable weather in Lisbon and off-peak tourist crowds. The best fares are often found by booking 6–8 weeks in advance and choosing midweek travel dates; avoid the Canadian Thanksgiving weekend for lower prices and smoother airport experiences. If you prefer nonstop convenience, book as soon as nonstop flights appear on sale — these seats are limited. For the best combination of price and experience, travel in early-to-mid October and return before late-month holiday spikes or major events.

Nonstop flights from Montréal-Pierre Elliott Trudeau International Airport (YUL) to Humberto Delgado Airport (LIS) minimize travel time (about 7 hours) and reduce the chance of missed connections, making them ideal for travelers prioritizing comfort and speed. Connecting flights often cost less and offer more schedule flexibility, routing through hubs like Toronto, New York, or major European airports — but they increase total travel time and add layover risk. In October, weigh cost savings against potential weather-related delays during shoulder-season travel; if saving money is the priority, accept a one-stop itinerary and longer transit time. Always leave ample connection time when booking multi-leg itineraries and choose reputable carriers with good on-time records.

TAP Air Portugal: Often offers competitive transatlantic fares and direct access to Lisbon with strong connectivity across Portugal, plus generous award options for Star Alliance partner airlines. Air Canada: Good frequency from Montreal and codeshare partnerships to reach Lisbon via partner routes; often reliable for baggage policies and lounge access for elites. Air Transat: Seasonal and budget-friendly transatlantic leisure service with competitive fares and economy-focused service; premium economy options available on some routes. WestJet and other carriers may provide connecting itineraries via Canadian or U.S. hubs. In October, compare total trip time, checked baggage policies, onboard meal service, and seat comfort — then book the carrier that best matches your budget and schedule needs.

Packing and clothing: Layer for autumn travel — light sweaters, a waterproof jacket, and comfortable walking shoes for Lisbon’s cobblestones. Timing and daylight: Europe typically shifts clocks in late October for daylight savings — double-check arrival local times to avoid missed transfers. Booking and fares: Book 6–8 weeks ahead for the best October fares, and avoid Canadian Thanksgiving travel dates when possible. Health and safety: Carry photocopies of travel documents, register travel plans if required, and review any health advisories before departure. Local logistics: Purchase metro cards at Humberto Delgado Airport (LIS) for convenient city travel, and prebook popular day trips (Sintra, Douro wine tours) to ensure availability during October.

Nonstop flight time from Montréal-Pierre Elliott Trudeau International Airport (YUL) to Humberto Delgado Airport (LIS) typically ranges from 6 hours 50 minutes to about 7 hours 30 minutes, depending on wind and routing. When nonstops are not available or are limited, common one-stop connections route through Toronto (YYZ), New York (JFK/EWR), or European hubs like Madrid and London, extending total travel time to 10–14 hours including layovers. In October, aim for flights that arrive in Lisbon in the afternoon or early evening to maximize same-day transfers and hotel check-in; early-morning transatlantic departures from YUL often correspond to afternoon arrivals at LIS the same day. Use airline timetables and aggregator filters to view nonstop, one-stop, and multi-leg schedules and pick the best balance of price and total journey time.

To find cheap flights from Montréal-Pierre Elliott Trudeau International Airport (YUL) to Humberto Delgado Airport (LIS) in October, start by searching 6–10 weeks ahead and use flexible-date calendars to spot the lowest fares. Midweek departures (Tuesday–Thursday) often yield lower prices than weekend travel and help avoid Canadian Thanksgiving price spikes. Compare nonstop vs one-stop itineraries — one-stop options via major hubs (Toronto, New York, Lisbon connections) can shave costs but increase travel time. Sign up for fare alerts, set price trackers for YUL to LIS routes, and check low-cost transatlantic carriers or seasonal charter services.
