During December holiday travel, arrive at least 2.5 to 3 hours before international departures from Seattle-Tacoma International Airport (SEA) to allow for check-in, security, and potential weather delays.

Midweek departures (Tuesday–Thursday) often offer lower fares and less airport congestion. If you need to travel during peak holiday windows (December 20–31), book as early as possible, monitor price alerts, and consider red-eye or early-morning flights for steadier on-time performance.

Choosing between direct (nonstop) and connecting flights from Seattle-Tacoma International Airport (SEA) to Guadalajara International Airport (Miguel Hidalgo y Costilla) (GDL) depends on priorities: nonstop saves time (approx 4.25–4.75 hours) and reduces connection risk, but can cost more during December holidays. Connecting flights via hubs like Los Angeles (LAX), Phoenix (PHX), or Dallas/Fort Worth (DFW) often reduce fares and increase schedule options. For holiday travel in December, weigh the value of a nonstop seat to avoid missed connections against potential savings on one-stop itineraries.
Key carriers for SEA–GDL travel include Alaska Airlines (often offering seasonal nonstop service), Aeromexico (one-stop via MEX), and various Mexican low-cost carriers on seasonal or connecting routes. Alaska typically provides strong West Coast connectivity and generous frequent-flyer benefits within its network; Aeromexico offers broader Mexican domestic connections through Mexico City; low-cost carriers can offer lower fares but assess baggage and seat fees carefully. During December, compare total trip time, baggage policies, change fees, and loyalty benefits to determine the best carrier for your needs.
