Takeoff from OPO
LEFTOPO's runway sits just west of Porto city, so climbing out on the prevailing southerly departure and turning back toward the north puts the Douro River estuary, Foz do Douro, and the Atlantic coastline right beneath the left-side windows. The right side mostly shows inland farmland with less definition.

Landing at LGW
RIGHTArrivals into Gatwick from the south typically cross Sussex and Surrey before turning to line up on runway 26, and on a clear day the London skyline is visible in the distance to the north on the right side. The left side during this same turn faces mostly open countryside with fewer distinguishing features.
