Sit on the Left side of the plane for the best views on flights from London to Boston. Left side wins at both ends of this flight. Over London during departure you get the Thames and city skyline, and on approach into Boston you get the harbor and downtown skyline. The transatlantic cruise portion over Greenland and Labrador offers similar views on both sides, so the departure and arrival experiences tip the balance firmly to the left.

During takeoff from Heathrow (LHR), sit on the Left side for the best views. Heathrow typically departs westbound on runways 27L/27R, then aircraft turn right (northbound) climbing out over west London. Left side seats get views over central London as the aircraft banks — you can see the Thames snaking through the city, the City of London skyline, and Canary Wharf tower cluster clearly. Right side faces suburban west London and the M25 corridor, which is far less interesting. Notable sights include: River Thames bends through central London, Canary Wharf tower cluster, Windsor Castle and Windsor Great Park to the southwest, M25 motorway ring visible as a grey arc.

When landing at General Edward Lawrence Logan International (BOS), sit on the Left side for the best views. Logan Airport sits on a peninsula in Boston Harbor, and aircraft typically approach from the southwest on runway 04R/04L or from the northwest on runway 33L. On a southwest approach, left side seats look directly over Boston Harbor, the downtown Boston skyline, and the Charles River. Right side faces the open Atlantic or South Boston industrial areas with far less visual interest. Notable sights include: Boston Harbor islands, downtown Boston skyline including Prudential Tower and John Hancock Tower, Charles River and Cambridge, Cape Cod peninsula visible to the south on clear days.

The flight from Heathrow (LHR) to General Edward Lawrence Logan International (BOS) takes Approximately 7 to 8 hours westbound.

The flight path typically tracks northwest over Ireland (Shannon area visible on clear days), then across the North Atlantic. Southern tip of Greenland's ice sheet and fjord coastline is often visible roughly 3 to 4 hours in. Labrador and Newfoundland coastlines appear about 5 hours in — rocky, lake-studded boreal landscape. The Gulf of St. Lawrence and Nova Scotia coastline precede the New England coast on descent.
