Best Time to Book
Book flights from Dallas to Seattle 56 days before departure for the best prices; waiting longer leads to significantly higher costs.
To secure the best deal on flights from Dallas to Seattle, aim to book your ticket about 56 days before your departure. Prices are typically lowest around this time, with ranges averaging $261. If you wait longer, prices can spike significantly, reaching up to $458 if booked earlier or escalating quickly after 19 days, where costs could soar from $310 to as much as $497.

If you're already within 56 days, book your flight as soon as you can to avoid higher fares.
