Sit on the Right side of the plane for the best views on flights from Billings to Pendik, Istanbul. While the Billings departure offers dramatic mountain scenery, the Istanbul landing provides superior visual variety and landmark density. The approach crosses two major water bodies (Sea of Marmara and Bosphorus strait) and descends into one of the world's most geographically distinctive cities straddling two continents. The water features, urban density, and geographic complexity of the approach outweigh the mountain drama of the departure, giving the right side a higher overall score.

During takeoff from Billings Logan International Airport (BIL), sit on the Left side for the best views. Billings sits on the northern edge of the Yellowstone Plateau with the Beartooth Mountains and Absaroka Range visible to the south and southwest during climb-out. Left-side departures capture these dramatic peaks immediately after takeoff. Notable sights include: Beartooth Mountains (south-southwest), Absaroka Range (south), Yellowstone Plateau terrain, Billings urban area.

When landing at Istanbul Sabiha Gökçen International Airport (SAW), sit on the Right side for the best views. The approach to Istanbul Sabiha Gökçen crosses the Sea of Marmara and the Bosphorus strait, with the Asian side of Istanbul's urban sprawl, the Golden Horn waterway, and the Anatolian plateau visible during descent. Right-side seats capture the water features and city density most effectively. Notable sights include: Sea of Marmara (western approach), Bosphorus strait, Istanbul's Asian districts and harbor infrastructure, Anatolian plateau.

Approaching Europe, the route crosses the British Isles or northern France, then continues southeast over the Alps (visible on clear days), the Balkans, and the Carpathian Mountains before descending into the Black Sea region and approaching Istanbul from the northwest over the Sea of Marmara.
