Sit on the Left side of the plane for the best views on flights from Washington to Doha. Both sides score equally for the full flight due to the transatlantic/transcontinental nature of the route with extended ocean crossing (approximately 5+ hours over Atlantic and Mediterranean). However, left side edges ahead for takeoff scenery from DCA with recognizable Washington landmarks, while right side offers better landing approach into Doha. Left wins marginally for the superior departure experience from a major U.S. capital city.

During takeoff from Ronald Reagan Washington National (DCA), sit on the Left side for the best views. Left side captures the Potomac River, Washington Monument, and Capitol Building during departure from DCA. The airport sits directly on the river, making the immediate departure corridor scenic with urban landmarks and water features visible within the first 10-15 minutes of flight. Notable sights include: Potomac River, Washington Monument, U.S. Capitol Building, Arlington National Cemetery.

When landing at Doha International (DOH), sit on the Right side for the best views. Right side offers the approach into Doha with views of the Persian Gulf coastline, Doha's harbor with its distinctive dhow-filled anchorages, and the modern skyline of West Bay district. The final descent provides clear views of the coastal development and the airport's position on the peninsula. Notable sights include: Persian Gulf, Doha Harbor, West Bay skyline, Doha International Airport runway.

The flight from Ronald Reagan Washington National (DCA) to Doha International (DOH) takes 10h 15m.

Transatlantic crossing over the Atlantic Ocean (6+ hours with no visible landmarks), European coastline including southern Spain and Portugal, Mediterranean Sea, North African coast near Morocco/Algeria, crossing into Middle East airspace over Libya/Tunisia region, eventual approach to Persian Gulf with Arabian Peninsula visible before Doha descent
