Spokane is served by Spokane International Airport (GEG), the primary and largest airport in Eastern Washington and the Inland Northwest. GEG offers a robust selection of nonstop arrival routes from major hubs and key destinations across the western and central United States into GEG, providing essential connectivity without the need to travel through Seattle for many arrivals.
The most frequent and competitive arrival routes to Spokane (GEG) connect from major airline hubs. Top departure points include Seattle (SEA), Denver (DEN), Las Vegas (LAS), Phoenix (PHX), Salt Lake City (SLC), Minneapolis (MSP), and Chicago (ORD) into GEG. These routes provide access from vast domestic and international networks into Spokane. For travelers seeking direct arrivals from East Coast cities or a wider variety of international options into the region, comparing fares into Seattle-Tacoma International Airport (SEA), a 4-5 hour drive from Spokane, may occasionally be worthwhile — fly into SEA on a competitive long-haul route, then take ground transport or a connecting flight to Spokane.
Spokane's airport is served by a healthy mix of major and low-cost carriers flying into GEG. Key airlines include Alaska Airlines (with a strong presence and multiple daily flights from SEA), Delta, Southwest, United, American, and Allegiant Air into Spokane. Southwest and Allegiant provide significant low-fare competition on popular leisure arrival routes like from Las Vegas, Phoenix, and Oakland into GEG.
To secure cheap flights to Spokane, book domestic arrivals at least 3-5 weeks in advance into GEG. Utilize the competition between Alaska, Delta, and Southwest on core arrival routes like from Seattle and Denver into Spokane. Always check Allegiant for direct, low-fare options into GEG from leisure destinations, but remember to account for their à la carte pricing model. For the best deals into Spokane, fly mid-week (Tuesday through Thursday) into GEG and be flexible with your arrival dates, as fares can vary significantly based on demand from both business and leisure travelers.
