Sit on the Right side of the plane for the best views on flights from Billings to Istanbul. While the Billings departure offers immediate mountain scenery, the Istanbul landing provides more dramatic and varied geography: the Bosphorus Strait is a globally iconic waterway with sharp visual definition, the Golden Horn adds urban-waterfront complexity, and the Marmara Sea crossing during cruise offers sustained coastal views. The right side captures the approach to one of the world's most geographically distinctive cities. The left side's Yellowstone Plateau terrain, though scenic, is relatively subdued and becomes monotonous over the long cruise phase across the Great Plains and Canadian prairies.

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 departure offers immediate mountain terrain. Notable sights include: Beartooth Mountains (south), Absaroka Range (southwest), Yellowstone Plateau escarpment, Billings urban area and Rimrock.

When landing at Ataturk (IST), sit on the Right side for the best views. The approach to Istanbul crosses the Bosphorus Strait and enters the Marmara Sea with the European and Asian coastlines converging. Right-side descent offers views of the Bosphorus narrows, the Golden Horn inlet, and Istanbul's dense urban waterfront as the aircraft descends toward Atatürk Airport on the European shore. Notable sights include: Bosphorus Strait (north-south waterway), Golden Horn (inlet on European side), Marmara Sea, Istanbul urban sprawl and harbor infrastructure.

The flight from Billings Logan International Airport (BIL) to Ataturk (IST) takes 13h 20m.

Great Plains and Canadian prairies (flat, minimal landmarks for 4-5 hours); Hudson Bay region (tundra, sparse features); Labrador and Atlantic coast (rocky, sparse); Greenland ice sheet (if routed north; white expanse, minimal detail); North Atlantic open ocean (5-6 hours, featureless); Norwegian coast and North Sea (if routed via UK/Scandinavia); Alps or Carpathians (if southern routing); Balkans and Aegean approaches (if Mediterranean routing). Actual routing depends on jet stream and air traffic control; most BIL-IST flights route eastbound over Canada, Greenland, and the North Atlantic, with minimal scenic features during the 8-10 hour ocean crossing.
