Window Seat

Seattle → New York

SEA–JFK · Seattle–Tacoma International Airport to John F. Kennedy International Airport

Best bet

Either side

Both sides workThe two sides come out close to level.

Both sides have something going for them, and the totals come out close enough that picking one would be a coin flip with extra steps.

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 JFK: 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.SEAJFKLEFT SIDERIGHT SIDE123456
Distance from the route is to scale (up to 63 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

    RightEarly44 mi off the route

    Mount Rainier is about 44 miles off the right, early in the flight.

    Good possibility

  2. Glacier Peak

    LeftEarly39 mi off the route

    Early in the flight, Glacier Peak sits roughly 39 miles to the left.

    Distant possibility

  3. Flathead Lake

    Either sideQuarter in5 mi off the route

    Flathead Lake passes almost directly beneath about a quarter of the way in, which is the one place a window seat can't help you.

    Good possibility

  4. Glacier National Park

    Glacier National Park is about 63 miles off the left, about a quarter of the way in.

    Distant possibility

  5. Sleeping Bear Dunes

    About three quarters of the way, Sleeping Bear Dunes sits roughly 20 miles to the left.

  6. Manhattan

    Whether Manhattan appears comes down to how you come into JFK, which is not something we can know in advance.

    Runway dependent

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?

New York → SeattleEither 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.
