Window Seat

Seattle → Salt Lake City

SEA–SLC · Seattle–Tacoma International Airport to Salt Lake City International Airport

Best bet

Right side

Strong betOne side has clearly more to look at.

Mount Rainier is the main event, and it has company: 3 more worth looking at out the right.

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.

SEA to SLC: where each landmark sits relative to the routeA diagram of the representative route running left to right, with the departure airport at the left and the arrival airport at the right. Landmarks on the left side of the aircraft are plotted above the route line and landmarks on the right side below it, each at its distance from the route. The numbered list below this diagram carries the same information as text.SEASLCLEFT SIDERIGHT SIDE1234567
Distance from the route is to scale (up to 94 miles); the shaded ends are the 40-mile zones around each airport where the runway in use decides the view. Numbers match the list below. Hollow markers didn't count toward the recommendation.

  1. Mount Rainier

    RightEarly16 mi off the route

    Mount Rainier is about 16 miles off the right, early in the flight.

    Strong candidate

  2. Mount St. Helens

    RightEarly64 mi off the route

    Early in the flight, Mount St. Helens sits roughly 64 miles to the right.

    Distant possibility

  3. Mount Adams

    RightEarly43 mi off the route

    Look right early in the flight for Mount Adams, about 43 miles out.

    Distant possibility

  4. Mount Hood

    Mount Hood is about 94 miles off the right, about a quarter of the way in.

    Distant possibility

  5. Wallowa Mountains

    Around the halfway mark, Wallowa Mountains sits roughly 34 miles to the left.

    Distant possibility

  6. Sawtooth Range

    Look left about three quarters of the way for Sawtooth Range, about 49 miles out.

    Distant possibility

  7. Great Salt Lake

    Either sideNear the end4 mi off the route

    Great Salt Lake passes almost directly beneath late in the flight, which is the one place a window seat can't help you.

    Strong candidate

The sun

Flying soon? Add your date and departure time and we'll work out where the sun should be, and which side gets less of it.

Airport codes or city names. SEA, Seattle, and Seattle-Tacoma all work.

Skip the date and you still get the landmark answer. Add it and we work out where the sun will be, using the departure airport's local time.

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?

Salt Lake City → SeattleLeft side

Calculated 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.
