Flight Deals from Dallas to Seattle from $70

When planning your flight from Dallas to Seattle, keep in mind that prices vary significantly throughout the year. The highest average rates occur in early to mid-April, particularly around early April when prices peak at their highest with an average around $1248. Conversely, late August through mid-October tends to offer lower fares, with the lowest recorded at around $130 in late April. Notably, prices surge after the holidays in early January, remaining high until mid-March, with a rapid decline approaching late March and into early April, before rising sharply again in April.

If you're planning to fly from Dallas to Seattle, the best time to buy your tickets is about 83 days before your departure, when prices are around $272. It's crucial to book at least 22 days in advance, as prices surge significantly after that, climbing from $300 to as high as $476 right before your flight. Booking earlier may seem appealing, but prices can reach up to $413, which is 52% higher than the optimal time. While last-minute deals might pop up, they often come with higher prices and limited options. Thus, if your departure is already less than 83 days away, securing your ticket as soon as possible will save you money.
