Window Seat

Las Vegas → Philadelphia

LAS–PHL · Harry Reid International Airport to Philadelphia 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 San Juan Mountains, 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.

LAS to PHL: 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.LASPHLLEFT SIDERIGHT SIDE12345678
Distance from the route is to scale (up to 53 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. Lake Mead

    Either sideEarly3 mi off the route

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

    Strong candidate

  2. Zion National Park

    LeftEarly35 mi off the route

    Early in the flight, Zion National Park sits roughly 35 miles to the left.

    Distant possibility

  3. Grand Canyon

    RightEarly53 mi off the route

    Look right early in the flight for Grand Canyon, about 53 miles out.

    Distant possibility

  4. Lake Powell

    Either sideEarly7 mi off the route

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

    Strong candidate

  5. Monument Valley

    Early in the flight, Monument Valley sits roughly 26 miles to the right.

    Good possibility

  6. San Juan Mountains

    Look left about a quarter of the way in for San Juan Mountains, about 8 miles out.

    Good possibility

  7. Sangre de Cristo Mountains

    Sangre de Cristo Mountains is about 51 miles off the right, about a quarter of the way in.

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?

Philadelphia → Las VegasRight 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.
