Sit on the Left side of the plane for the best views on flights from London to Shannon. While the right side wins at takeoff, the left side delivers the more dramatic scenery overall. Once airborne and tracking northwest over Wales and the Irish Sea, left-side passengers see the Welsh coastline, Cardigan Bay, and the full approach over the Shannon Estuary and the Burren. The landing views on the left are genuinely spectacular on a clear day.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow typically departs westbound on runways 27L/27R. A right-side seat gives you views south over Windsor Great Park, the Thames valley, and the M25 corridor as you climb out heading west. Left side faces north toward Slough and the less scenic suburban sprawl. Notable sights include: Windsor Castle and Windsor Great Park, Thames river bends near Staines, M25 motorway arc, Wraysbury Reservoir complex.

When landing at Shannon (SNN), sit on the Left side for the best views. Shannon airport sits on the south bank of the Shannon Estuary, and aircraft typically approach from the east on runway 24 or from the northeast. A left-side seat gives you the broad Shannon Estuary, Lough Derg, and the Burren limestone plateau as you descend over County Clare. Right side faces south toward less distinctive farmland. Notable sights include: Shannon Estuary, Lough Derg, the Burren limestone plateau, Cliffs of Moher (visible on clear days to the northwest).

The flight from Heathrow (LHR) to Shannon (SNN) takes Approximately 1 hour 20 minutes.

The flight tracks northwest from London, crossing the Brecon Beacons and Cambrian Mountains of Wales, then Cardigan Bay and the Irish Sea before making landfall over County Clare. The Welsh coastline and the broad expanse of the Irish Sea are the dominant mid-flight features. On clear days the Wicklow Mountains of Ireland's east coast may be glimpsed before the aircraft turns southwest toward Shannon.
