Whether you're heading up for a weekend of coffee and Pike Place Market or planning a longer hiking trip into the Cascades, this guide breaks down everything you need to know to snag the best fare and make the 1,100-mile journey a breeze.

Direct vs. Connecting Routes

Most travelers prefer the direct route because three hours in the air is much better than a long layover. However, if direct flights are expensive, consider connections through Las Vegas (LAS), Salt Lake City (SLC), or Denver (DEN). A short stop in Vegas can sometimes save $100 or more.

Tips for Booking the Cheapest Seat

• The 21-Day Rule: Book at least three weeks in advance to avoid price spikes.
• Mid-Week Magic: Tuesday and Wednesday flights are usually cheaper than weekends.
• Morning vs. Evening: Early morning departures are often the cheapest and most reliable.
