St. Louis to Bucharest is 5,455 miles (8,779 km), a flight of about 10 hours.
Right seats offer the superior experience: eastbound departure over the Mississippi River valley and Illinois landscape, then the transatlantic crossing provides views of the Atlantic, and the approach to Bucharest on a westbound arrival would position right seats to see the Danube and Wallachian Plain. The takeoff view is particularly strong.
Flight Path
The flight crosses the Atlantic Ocean for roughly 5-6 hours. Notable features include: the Appalachian Mountains (visible during initial eastbound climb if departing on Runway 30), the Atlantic coastline near North Carolina or Virginia (receding below), the Mid-Atlantic Ridge (not visible but crossed at altitude), the Irish coast and Celtic Sea (approaching Europe after 7-8 hours), the British Isles (potentially visible to the north depending on exact routing), and the North European Plain before descending into Romania. The Carpathian Mountains may be visible on the final approach to Bucharest, appearing as a distant ridge on the horizon to the north and west.
