Window Seat

San Diego → Denver

SAN–DEN · San Diego International Airport to Denver International Airport

Best bet

Left side

Slight edgeEnough to break a tie, not enough to change seats over.

It is close. The left edges it, mostly on Grand Canyon, but the right is not a bad seat.

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.

SAN to DEN: 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.SANDENLEFT SIDERIGHT SIDE1234567891011
Distance from the route is to scale (up to 50 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. San Jacinto Peak

    LeftEarly40 mi off the route

    San Jacinto Peak is about 40 miles off the left, early in the flight.

    Distant possibility

  2. Salton Sea

    RightEarly16 mi off the route

    Early in the flight, Salton Sea sits roughly 16 miles to the right.

    Good possibility

  3. San Francisco Peaks

    RightHalfway48 mi off the route

    Look right around the halfway mark for San Francisco Peaks, about 48 miles out.

    Distant possibility

  4. Grand Canyon

    LeftHalfway8 mi off the route

    Grand Canyon is about 8 miles off the left, around the halfway mark.

    Strong candidate

  5. Lake Powell

    LeftHalfway35 mi off the route

    Around the halfway mark, Lake Powell sits roughly 35 miles to the left.

    Distant possibility

  6. Monument Valley

    Either sideHalfway6 mi off the route

    Monument Valley passes almost directly beneath around the halfway mark, which is the one place a window seat can't help you.

    Strong candidate

  7. San Juan Mountains

    RightThree quarters19 mi off the route

    San Juan Mountains is about 19 miles off the right, about three quarters of the way.

    Good possibility

  8. Maroon Bells

    LeftThree quarters20 mi off the route

    About three quarters of the way, Maroon Bells sits roughly 20 miles to the left.

    Distant possibility

  9. Mount Elbert

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

    Good possibility

  10. Pikes Peak

    Pikes Peak is about 50 miles off the right, late in the flight.

    Distant possibility

    Late in the flight, Longs Peak sits roughly 49 miles to the left.

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?

Denver → San DiegoRight 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.
