When planning your flights from Dallas to Montreal, consider that the most expensive times to fly generally span from late January through early March and again from late April to early June, with prices peaking in mid-February at around $900-960. Conversely, you'll find the best deals from mid-August to late September, and again in mid-October, with prices dropping to around $600-640 during these periods.

Best Time to Book
Book your flight from Dallas to Montreal 105-110 days in advance for the best prices, as costs rise significantly closer to departure.
When planning your trip from Dallas to Montreal, the best time to buy your tickets is between 105 to 110 days before departure, where prices hover around $546. This is the most affordable period, with prices steadily increasing after that point. If you book too early, prices can reach up to $666, indicating a 22% increase compared to waiting for that ideal moment. As you approach the departure date, expect prices to rise, reaching peaks of around $800 if booked last minute, which is 43% higher than the optimal purchase window. Therefore, if your travel is within 105 days, act quickly to secure the best deal.
