THE FLIGHT IS ONLY PART OF THE TRIP
Arriving in Montreal.
Airport context and source-backed details to help you compare the whole journey.
YUL · Montreal / Pierre Elliott Trudeau International Airport
This page searches YUL — Montreal / Pierre Elliott Trudeau International Airport. Airport coverage follows the destination city market in the passenger dataset, with minor airports excluded. Always check the airport code on both legs: a city search can include different arrival airports, and the cheapest option may not be closest to where you are staying.
BTS recorded 171,496 scheduled passengers departing O’Hare and Midway for this destination city market from 2025-07 to 2026-06. That puts it at number 70 in our selected ranking. These are historical on-flight market passengers, not unique travelers, current flight frequencies or a measure of search popularity.
The airport reference places Montreal / Pierre Elliott Trudeau International Airport in Montréal, Canada, at 45.468°, -73.742°. Use the airport’s official information to plan your arrival and return journey. Our fare table compares air travel only; ground transfers, luggage and accommodation can change the total trip budget.
These are planning links, not priced offers. Hotel and car availability is checked by the provider. We currently receive no commission from these links.
GOOD QUESTIONS. STRAIGHT ANSWERS.
Before you take off for Montreal.

What is the cheapest flight to Montreal you have recorded?+
The lowest seven-night round-trip search fare in our archive is $366, recorded Sep 27, 2026 for ORD to YUL, Dec 2–Dec 9, 2026. Our route archive starts Sep 27, 2026. This is our observed record, not an industry-wide all-time low, a verified booking price or a current offer.
How much are cheap flights from Chicago to Montreal?+
Our lowest current seven-night sample is $366 round trip for one adult in economy, from ORD to YUL, Nov 6–Nov 13, 2026. It was checked Sep 27, 2026. This is a dated search result, not a guaranteed ticket price; confirm the return and full fare conditions before paying.
Is O’Hare or Midway cheaper for Montreal?+
For the matched Nov 6–Nov 13, 2026 search, ORD had the lowest sample at $366. The highest and lowest airport fares were $119 apart. That applies to those dates and settings only. Try other matched dates and add your own ground transport cost in the airport calculator above.
Can I fly nonstop from Chicago to Montreal?+
The current sample includes a nonstop outbound from ORD to YUL on Nov 6, 2026, with a round-trip search fare of $366. Check the return direction separately: a nonstop outbound does not guarantee a nonstop return.
What is the cheapest month to fly to Montreal?+
The travel-period chart compares only the dates we sampled. It cannot establish the cheapest month of the year. Start with a promising sampled period, then check nearby dates with the same trip length. The separate history chart tracks one specific search over time; it is not a travel calendar.
Which Montreal airport should I choose?+
This destination market includes Montreal / Pierre Elliott Trudeau International Airport (YUL). Check the exact arrival code on the fare you choose, then compare the onward journey to your accommodation. The arrival section links airport information and our source-backed planning notes.
Will Skyscanner show the same price as Google Flights?+
Not necessarily. The buttons open separate searches with matching airports and dates when a dated sample is available. Providers can show different airlines, sellers, baggage rules and live prices. The sampled Google Flights price is never a Skyscanner quote.
Are bags, hotels and rental cars included?+
Do not assume bags are included unless the provider explicitly confirms them. Our research shows flight search fares; the accommodation and rental-car links are separate planning tools. Compare the final total, cancellation terms and location before booking any part of the trip.
This page contains 170 current search-result observations across 24 airport/date searches. Route research is compiled by the Chicago Flight Research desk from the sources below.
