37,000+ Flights: These Are Turkish Airlines' Busiest Routes

In October 2025, Turkish Airlinesscheduled over 37,000 passenger flights, maintaining its title as one of the world’s busiest international carriers, according to Cirium, an aviation analytics company. The Istanbul-based airline continues to rely heavily on its domestic and regional operations, which account for the majority of departures, to feed its growing global network. It has a fleet of more than 400 aircraft and serves more than 350 destinations in over 120 countries.

Turkish Airlines holds the world record for the most destinations served worldwide, and exemplifies how a carrier can combine local dominance with global reach. While its long-haul routes attract international travelers, the airline’s highest flight frequencies remain concentrated on short-haul sectors, particularly those linking Istanbul with major Turkish cities and nearby international markets. This mix of dense domestic flying and long-haul connectivity highlights its ‘bridge between continents’ strategy.

Together, these routes accounted for nearly 6,500 flights last month, underlining how Turkish Airlines relies on its domestic and near-regional network to sustain passenger flows. Notably, the first four routes are all domestic, emphasizing Turkey‘s vast internal air demand.

“One of our goals is to connect every corner of Turkey with the world through Istanbul,” a Turkish Airlines spokesperson told Simple Flying during a press conference in Stockholm earlier this month. Turkey is home to 22 UNESCO World Heritage Sites, most of which can be reached via Turkish Airlines’ extensive network.

Fleet & Operational Strategy

Turkish Airlines operates one of the most diverse short-haul fleets in Europe, centered on the Airbus A320 family, including neo variants, as well as Boeing 737-800/900, and MAX models. These types dominate high-frequency domestic and regional routes, as well as short-haul international routes, offering capacity for 150 to 200 passengers. Their efficiency and quick turnaround times make them ideal for dense daily operations such as Istanbul–Antalya or Istanbul–Ankara.

The airline’s widebody aircraft, including the Airbus A330-300, Airbus A350-900, Boeing 777-300ER, and Boeing 787-9 Dreamliner, are typically deployed on longer international sectors. However, they occasionally appear on high-demand domestic routes during holidays to balance capacity. By maintaining extensive narrow-body operations across Turkey, Turkish Airlines maximizes feed into its Istanbul hub, which then connects passengers onward to Asia, Africa, Europe, and the Americas.

This structure mirrors that of Emirates or Qatar Airways, ensures that even smaller Turkish cities benefit from connectivity. Per Anadolu Agency, Istanbul Airport handles nearly 1,400 daily movements and is now among the world’s top ten busiest hubs. The country’s geography allows most domestic destinations to be reached in under two hours, enabling same-day return trips and tight international connections. Turkish Airlines’ domestic dominance thus plays an integral role in supporting its long-haul profitability.

Beyond its core domestic strength, Turkish Airlines continues to broaden its global footprint. Recently, the airline confirmed the resumption of flights to Aleppo and Damascus, Syria, its first scheduled service to the war-torn country in over a decade. Additionally, it announced new flights to Phnom Penh (Cambodia), set to launch later this year, marking its first entry into that market.

Since 2023, Turkish Airlines has restored or inaugurated flights to Detroit, Denver, Osaka, Palermo, Melbourne, Sidney, and others, alongside increasing frequencies to Africa and the Middle East. The rapid rise of Çukurova Airport (COV), now among the top four busiest domestic routes, demonstrates how new regional infrastructure quickly integrates into the airline’s network strategy.

As of October 2025, Turkish Airlines’ operation combines massive domestic scale, an evolving fleet mix, and continuous global expansion. With more than 37,000 monthly flights, led by high-frequency domestic operations using 737s and A321s, and upcoming launches in new international markets, the carrier’s momentum shows no signs of slowing.
