Sit on the Left side of the plane for the best views on flights from Dublin to London. Left side delivers the best views at both ends of the flight — Dublin Bay and the Wicklow Mountains on departure, and the Surrey Hills on approach to Gatwick. Over the Irish Sea and Wales the left side also faces south, giving slightly better light and occasional glimpses of the Welsh coastline and Brecon Beacons in the distance.

During takeoff from Dublin (DUB), sit on the Left side for the best views. Dublin typically departs eastward on runway 28/10, and a left (south-facing) seat gives you views over Dublin Bay, the Poolbeg chimneys, and the Wicklow Mountains as you climb out and bank southeast. The city centre and port are clearly visible before the aircraft heads over the Irish Sea. Notable sights include: Dublin Bay and Poolbeg Peninsula, Wicklow Mountains to the south, Dublin city centre and the Liffey estuary, Howth Head peninsula.

When landing at Gatwick (LGW), sit on the Left side for the best views. Gatwick predominantly lands on runway 08R/26L, meaning aircraft approach from the east or depart westward. On an approach from the northwest, a left seat faces south and gives views over the Surrey Hills and the North Downs. The right seat on approach tends to face north toward less distinctive suburban sprawl. Notable sights include: Surrey Hills and North Downs escarpment, Crawley town below the final approach, the M23 motorway corridor, Ashdown Forest to the southeast.

The flight from Dublin (DUB) to Gatwick (LGW) takes Approximately 1 hour 20 minutes.

The flight crosses the Irish Sea, passing south of the Isle of Man, then crosses the Welsh coast near Aberystwyth or Cardigan Bay. It tracks over mid-Wales, crossing the Brecon Beacons and Black Mountains before entering England over the Severn Valley and the Cotswolds, then descending over Surrey toward Gatwick.
