Pack for cool, wet weather on arrival in Seattle and check airline change policies before booking. Book now to lock early-January deals and set alerts for last-minute fare drops.
Arriving at Seattle–Tacoma International Airport (SEA) in January requires planning for cool, wet conditions and occasional winter disruptions.

January often offers lower hotel prices outside peak tourist season — book accommodations near your arrival city early to secure the best rates.
January brings business conferences and smaller winter festivals to Seattle that can influence hotel availability and ground transport near Seattle–Tacoma International Airport (SEA). Guadalajara sees fewer major festivals in January but business travel to and from Mexico City may increase overall passenger flow at Guadalajara International Airport (GDL). If traveling around conference dates, book hotels and transport early and check flight schedules for heavier arrival windows.
For the best balance of price and service on the GDL–SEA route, fly mid-January on Tuesdays or Wednesdays when demand is lower. Early morning departures reduce the risk of afternoon weather delays at U.S. hubs, and booking 4–8 weeks ahead typically secures good January fares. If you need nonstop service, purchase earlier as direct seats are limited and may sell out during holiday spillover periods.

Choose nonstop for convenience and speed; pick connections for cost savings and expanded schedule options.
Alaska Airlines often provides the most reliable nonstop service on routes to Seattle and competitive on-board experience; Aeroméxico offers strong connectivity through Mexico City and frequent schedules.

Pack waterproof layers and an umbrella for Seattle’s January weather and bring a warm sweater for overnight flights. Choose flights with slightly longer layovers if your January itinerary connects through weather-prone hubs like LAX or MEX.
