Airbus A220-300 Seat Map

Because window spacing is set by the fuselage frames — about 20 inches on Boeing aircraft and 21 on Airbus — while seat pitch is something else, most often 29 to 31 inches. These numbers are never multiples of each other, so the windows drift against the rows: one row gets two windows, the next gets one that is off-center, and some row gets the wall panel between them at shoulder level. The tool works this out for every window seat and says so plainly, and in 3D you can see the panel with your own eyes. Which row it lands on depends on where the airline starts its cabin, so check when you board; but the effect belongs to the aircraft type, not to the flight.

Switch "Travelers" and the map highlights groups of adjacent seats in one row instead of single seats. The best ones are blocks your group fills completely: two on the pair by the wall of a wide-body with a 2-4-2 row, three on the window-side three of a 3-3 row. Then no stranger ends up beside you and nobody has to climb over someone else. If no row has that many seats together without an aisle, the tool shows a group across the aisle and says so.

Because every airline lays out the same aircraft type in its own way, and sometimes differently within its own fleet: an A320 may carry 150 seats or 186, with the exits in different rows. Writing "row so-and-so is the exit row" for a type would mean confidently misleading about half the readers. What does carry over is the physics: it is calmer over the wing, the last row does not recline, the galley is noisy. Where an airline layout could be verified, it is listed next to the type with the airline's name and a date. A layout gets on the list only if its seat count matches the sum over the rows: a guess here is worse than nothing.

Type its number into "Your seat" — for example, 23A. The map shows the seat and gives a card: pitch and width, how many windows the row gets, what is good about the seat and what is not. If you marked conditions, the card says in words whether the seat fits them. If the layout has no such number, your airline has a different row count: go by the properties instead — window or aisle, over the wing or in the tail, a lavatory nearby or not.

From the position of the Sun and the heading of the aircraft at points along the route, not only at the departure point. At each point the azimuth and altitude of the Sun are computed and compared with the heading: if the Sun is to the right of the heading, it shines into the right-hand windows. Because the whole route is used, a flight on which the Sun crosses from one side to the other is shown as shares, not as a single word. The departure time is read as local time at the departure airport — the way it is printed on the ticket.

For legroom, usually yes. For everything else, often no: it is colder by the door, the armrest generally does not lift because the tray table is inside it, nothing may stay at your feet for takeoff and landing, and on many aircraft the row in front of the exit does not recline. You will not be seated there with a child at all. If the goal is to sleep, a window seat away from the galley is almost always better.

The ride is smoothest over the wing, near the center of gravity: the farther from it, the more you feel the pitching, so the tail is the worst — for the same reason the end of a seesaw moves more than its middle. It is quietest ahead of the engines and away from galleys and lavatories. On a jet the noise grows toward the tail; on a turboprop the loudest spot is the row in line with the propellers, and that is a narrow band, not half the cabin.

Geometry, not the interior of a particular airline. The fuselage, wing, engines, tail, windows and seats are built from the same dimensions as the map, so 3D shows what depends on the shape of the aircraft: whether your seat gets a window or a wall panel, whether the wing is in the view, how close the galley and lavatory are. It does not show upholstery, screens or power outlets — every airline has its own.
