Paris (France) has a population of 2,161,000 and is located in the Île-de-France region of Europe. It's a significant city with good transport links and cultural offerings.
Rome (Italy) has a population of 2,873,000 and is situated in Lazio, Europe. This city serves as an important regional hub with solid connectivity.
Choose this route if your priority is reaching Paris (France) — a city of 2,161,000 in the Île-de-France region of Europe. Despite being the longer of the two at 2,256 km, it makes sense when Paris itself is the destination, the schedule fits better, or ticket prices are noticeably lower. Driving is realistic at this distance, with an estimated 2,933 km of road and a fuel cost band around $293 USD. The initial bearing is 302° (WNW), so a great-circle flight leaves Istanbul heading roughly WNW.
This route is the right call if you are heading to Rome (Italy) — a city of 2,873,000 in the Lazio region of Europe. It is also the shorter of the two at 1,375 km, saving about 1h 6min of flying and around 224 kg of CO₂ per passenger.

All distances on SnapDistance are calculated using the Haversine formula, which determines the great-circle distance between two points on Earth's surface. This gives the shortest possible distance over the globe, which is the measurement used for aviation and navigation. Actual travel distances by road or rail are typically 20-40% longer due to terrain, borders, and infrastructure routing. Flight times assume 800 km/h cruising speed with 30 minutes for takeoff and landing. Driving estimates use 80 km/h average speed with a 30% road distance factor.
