Best Time to Fly to Seattle
The sweet spot for flying to Seattle is spring (April-June) or fall (Sept-Oct). Mild temps (12-20°C), fewer crowds, and flights often dip below peak prices. Summer (July-Aug) is sunny but packed—hotels cost a lot more, Space Needle lines lol. Winter’s rainy and chilly (4-10°C), but flights/hotels can be steals if you don’t mind drizzle.
Hack: Fly Mon-Thurs for cheaper fares. Book 4-6 weeks early. Nonstop flights? Easy from most US hubs (2-5hrs). Pro tip: Alaska Airlines often has deals—Seattle’s their hub.
Where to Stay in Seattle
Book your Seattle hotel on Trip.com! Seriously, free cancellation + deals saved me last trip.
- Downtown/Pioneer Square: Walk to Pike Place, waterfront, museums. Perfect for first-timers.
- Capitol Hill: Hip cafes, nightlife, LGBTQ+ friendly. More budget stays + cool Airbnbs.
- Queen Anne: Quiet, views of the Space Needle, easy public transport. Slightly pricier but chill.
- Fremont: Quirky, artsy vibe. Breweries, troll statue, cheaper than downtown.
Avoid Sea-Tac airport hotels unless you’re crashing pre-flight. Traffic’s a beast—stay central!
