Finding cheap flights to Spokane WA feels a bit like trying to find a quiet corner in a downtown Seattle coffee shop—it takes a little scouting, but once you’re in, you’re golden. Honestly, most people just pull up a search engine, see a price that looks "okay," and pull the trigger. They end up paying $300 for a flight that probably should’ve cost $140.
Spokane International (GEG) is a fantastic, manageable airport, but it doesn't always play by the same rules as the massive hubs. If you're coming from the West Coast, you've got it easy. If you're flying in from the East or South, you basically have to treat this like a game of chess.
Why the "Golden Rule" of booking is dead
You’ve probably heard that booking on a Tuesday at 3:00 AM is the magic secret. It isn't. Not anymore. For 2026, the data from folks like Expedia and Google Flights shows that Sundays are actually the cheapest days to book domestic flights to Spokane, often saving you about 13% compared to a frantic Friday purchase.
But booking day matters less than your flying day.
If you can swing a Thursday departure, you're looking at a 16% price drop on average. Sunday returns? Those are for suckers or people with very strict corporate schedules. If you can push your return to a Monday or Tuesday, you’ll likely keep an extra fifty bucks in your pocket for a nice dinner at the Davenport.

The Airlines actually winning the "Cheap" game
A lot of people think Southwest is the default for a bargain. They’re good, don't get me wrong, and those two free bags are a lifesaver if you're bringing ski gear for Mt. Spokane. However, Allegiant Air has been aggressively undercutting everyone lately on specific routes.
Look at these recent 2026 price points:
- Las Vegas (LAS) to GEG: I’ve seen Allegiant run these for $78 round-trip.
- Denver (DEN) to GEG: Frontier often hits the $89 mark if you book at least 28 days out.
- Seattle (SEA) to GEG: This is the most popular route. Alaska and Delta basically have a boxing match over this corridor, with fares often hovering around $80-$90 one-way.
Beware the "Basic" trap
The catch with these ultra-low fares? Fees.
If you grab a $44 one-way on Frontier from Denver, remember they’ll charge you for everything short of the oxygen you breathe. By the time you add a carry-on, that "cheap" flight might actually be more expensive than a Delta or Alaska "Saver" fare that includes a overhead bin space.
When to visit Spokane (The "Value" Seasons)
If you want the absolute bottom-barrel prices, you go in February.

Is it cold? Yes. Is it snowy? Likely. But February is the official "low season" for GEG. According to ARC data, domestic flights booked at least a month in advance for February travel are roughly 24% cheaper than peak summer dates.
If you hate the cold, aim for September. The summer crowds have thinned out, the Lilac City is still beautiful, and prices take a significant dip before the holiday rush begins. Avoid July like the plague if you’re on a budget; it’s the most popular month and airlines know it.
The Hidden City Hack (Skiplagging)
This is controversial. Some people love it, airlines hate it.
"Hidden city ticketing" is when you book a flight from, say, Seattle to Minneapolis with a layover in Spokane. If the ticket to Minneapolis is cheaper than the direct flight to Spokane, you just get off at the layover and walk away.
Wait! Read this before you try it:

- Carry-on only: If you check a bag, it's going to Minneapolis. You aren't.
- One-way only: The second you skip a leg, the airline cancels the rest of your itinerary.
- Don't use your loyalty number: Airlines have been known to freeze frequent flyer accounts for doing this too often.
It's a "use at your own risk" maneuver, but for a last-minute trip where direct fares are astronomical, it can save you $200 in a heartbeat.
Proximity tricks: The Tri-Cities Alternative
Sometimes GEG just won't budge on price. If you’re truly desperate, check flights into Tri-Cities Airport (PSC) in Pasco.
It’s about a two-hour drive to Spokane. I’ve seen cases where flying into Pasco and renting a car was still $150 cheaper than flying directly into Spokane. It’s a bit of a trek, but the drive through the Palouse is actually pretty stunning, especially in the spring.
Actionable Steps for your Booking
- Set a Price Alert now: Use the Google Flights "Track Prices" toggle. Do not wait.
- Check Southwest separately: Their fares don't show up on most big comparison sites. You have to go to their website.
- The 28-Day Window: For domestic flights to Spokane, 28 days is the "sweet spot." Booking 27 days out? You might pay a $50 premium. Booking 6 months out? You're actually paying more than the "optimized" mid-range price.
- Look for the first flight: The 6:00 AM departures are usually the cheapest. They also have the lowest chance of being delayed because the plane is already at the gate from the night before.
Basically, if you stay flexible and avoid the Friday-to-Sunday travel trap, you can find cheap flights to Spokane WA without needing a miracle. Just keep your eyes on the "Saver" or "Basic" fine print so those baggage fees don't bite you at the gate.
Check the 28-day window on Google Flights tonight to see if your preferred dates have hit their "floor" price yet. If you see anything under $150 round-trip from a major West Coast hub, grab it—it rarely gets much lower than that.
