The flight path crosses the Celtic Sea and Irish Sea, passing west of Wales and southwest of the UK. At cruise altitude, you'll see the Atlantic coast of Wales (if visible through clouds), then the Bay of Biscay. The Iberian Peninsula comes into view as you approach Portugal, with the Portuguese coast becoming visible around 45 minutes before landing. The flight generally follows a direct southwest track across open water with limited landmark visibility in the midpoint, though the Welsh coast and eventual Portuguese coastline may be visible depending on weather and altitude.
