PDX–FCA · Portland International Airport to Glacier Park International Airport
Best bet
Left side
Good betA real difference, not a rounding error.
Mount Adams leads it, with 2 more on the same side.
Flight paths move around. Treat this as the better bet, not a promise.
What you might see
In flight order, with distance measured from the representative route.
Mount Hood
RightEarly34 mi off the routeMount Hood is about 34 miles off the right, early in the flight.
Good possibility
Mount St. Helens
LeftEarly28 mi off the routeEarly in the flight, Mount St. Helens sits roughly 28 miles to the left.
Good possibility
Columbia River Gorge
RightEarly11 mi off the routeColumbia River Gorge sits close enough to PDX that the runway in use and the procedure of the day decide whether it shows up at all.

- Landmarks that counted
That is the shortest path between the two airports, used as a representative corridor rather than a flight plan. The first and last 40 miles are treated as uncertain, because that part of the flight is shaped by the runway in use and the published departure or arrival procedure. Anything in those zones is listed and marked, never counted toward the recommendation.
Left and right, from where?
Left and right are from your perspective sitting in the cabin, facing the front of the aircraft. Seat letters are not a reliable guide to which side you are on, because aircraft are configured differently.
Why this isn't guaranteed
Flights don't follow the same path every day. Runway configuration, weather deviations, traffic, and air traffic control all move the track around, and none of it is knowable in advance. We also have nothing to say about cloud cover, which is the other thing standing between you and Mount Rainier. The full method.
Flying the other way?
Kalispell → PortlandRight sideCalculated from scratch, not by flipping this one. The landmarks arrive in the opposite order, the sun is somewhere else entirely, and the answer changes with them.
