Takeoff from LHR
LEFTHeathrow typically departs eastbound on runways 27L/27R (westerly wind operations) or 09L/09R heading east. On an eastbound departure toward Europe, the left (north) side gives you a clear view over central London — the Thames snaking through the city, the City of London skyline, and the sprawl of east London. The right side faces south toward Surrey suburbs with far less of interest.
Landing at OTP
LEFTBucharest's Henri Coandă Airport (OTP) primarily uses runway 08R/26L. On a westerly approach (landing runway 08R heading east), aircraft approach from the west-northwest, meaning the left side faces south toward Bucharest city center. The city's layout, the Dâmbovița river, and the Palace of the Parliament's enormous footprint are visible on the left during final approach. The right side faces north toward flat agricultural plains.
