Travel Tips
To maximize your comfort and savings on this popular route, aim to book your tickets at least three to five weeks before your intended departure date, as prices tend to climb sharply as the travel date approaches. Because both Austin (AUS) and Seattle (SEA) are major business centers, Monday mornings and Friday afternoons are often the busiest times at security checkpoints; choosing a mid-week flight on a Tuesday or Wednesday can often lead to a more relaxed airport experience and lower fares. Additionally, remember that weather in the Pacific Northwest can be unpredictable compared to the consistent heat of Austin, so packing a lightweight, waterproof jacket in your carry-on is highly recommended regardless of the season. Finally, take advantage of the Link Light Rail upon arrival in Seattle for a cost-effective and scenic $3.00 ride directly into the heart of downtown, bypassing the heavy traffic often found on the I-5 corridor.
