Seattle to London flight path: SEA to LCY

Sit on the Left side of the plane for the best views on flights from Seattle to London. Takeoff offers superior scenery with Mount Rainier and the Cascade Range as dramatic focal points. While landing provides London views, the Pacific Northwest departure is more visually striking and geographically distinctive.

During takeoff from Seattle Tacoma International (SEA), sit on the Left side for the best views. Left side offers immediate views of the Cascade Range and Mount Rainier during climb-out heading northeast over Washington state. Right side faces the Puget Sound and Olympic Mountains but with less dramatic relief. Notable sights include: Mount Rainier (14,411 ft, dominant volcanic peak), Cascade Range (north-south trending mountains), Puget Sound (water body to the west), Lake Washington (visible east of Seattle).

When landing at City (LCY), sit on the Right side for the best views. Right side provides views of the Thames River, central London landmarks, and the approach path over the English countryside. Left side faces away from the city during the typical eastbound descent into City Airport. Notable sights include: Thames River (winding through London), Central London urban grid (visible as dense building clusters), Essex countryside (agricultural fields and towns), North Sea coast (distant, on horizon).
