Discover the 6 Longest One-Stop Flights Scheduled for 2025

As global air travel evolves, several airlines continue to operate long one-stop routes due to various factors, including range limitations and economic considerations. In 2025, travelers will have the option of flying between cities separated by vast distances with just one layover, often at strategic hubs. These routes include fifth freedom services, allowing airlines to carry passengers between two foreign countries while stopping in a third. Utilizing data from Cirium, an aviation analytics company, here are the world’s six longest one-stop flights scheduled for 2025.

Singapore to New York-JFK via Frankfurt

The longest one-stop route in 2025 will connect Singapore to New York-JFK with a stop in Frankfurt, covering a distance of 8,903 nautical miles (16,489 kilometers). Singapore Airlines operates this route, which currently features double-daily nonstop flights using the Airbus A350-900ULR. This specialized variant is designed for maximum fuel capacity and includes a premium-heavy configuration, offering 67 business class and 94 premium economy seats.

For passengers traveling in first class or economy, the one-stop option utilizes the Boeing 777-300ER, which accommodates 264 passengers in a configuration with four first class seats, 48 business class seats, and 184 economy seats. The Singapore-Frankfurt leg is supported by a daily A380 service and additional Lufthansa flights, creating a robust network for travelers heading to New York.

Sydney to Rome via Perth

Qantas operates the second-longest one-stop route, flying from Sydney to Rome with a layover in Perth, spanning 8,984 nautical miles (16,639 kilometers). With the introduction of the Boeing 787-9, Qantas has transformed its Perth base into a key hub for European travel, offering nonstop flights to major destinations, including London and Paris.

The Sydney-Rome route features the same flight number for both segments, allowing passengers to experience seamless travel on the domestic leg. Launched post-COVID-19, this route serves not only the tourist market but also connects friends and family across continents.

Sydney to London-Heathrow via Singapore

With a distance of 9,274 nautical miles (17,176 kilometers), Qantas also operates a one-stop flight from Sydney to London-Heathrow via Singapore. This route remains essential due to the substantial distance separating the two cities, making nonstop flights economically challenging at present. Qantas operates a daily Airbus A380-800 for this journey, allowing for ticket sales between Sydney and Singapore, as well as London.

British Airways also serves this route, flying a Boeing 777-300ER daily, contributing to fierce competition among airlines. Both carriers must contend with a host of Asian airlines that operate connecting flights, making this route highly competitive.

Sydney to Paris via Perth

Another significant route from Qantas links Sydney to Paris with a stop in Perth, covering 9,475 nautical miles (17,548 kilometers). Following the launch of nonstop services to Paris from Perth, this route has gained traction, particularly among business travelers.

The same flight number applies to both legs, but aircraft assignments may vary, often depending on operational requirements. This route operates year-round, showcasing its importance in connecting Australia with one of Europe’s major business hubs.

Beijing to São Paulo via Madrid

Air China connects Beijing to São Paulo with a stop in Madrid, covering 9,494 nautical miles (17,582 kilometers). Operating three times weekly, this route serves as the carrier’s only link to South America and features a Boeing 787-9 configuration with 293 seats.

This route not only facilitates travel between the two cities but also emphasizes China’s strategic interest in strengthening ties with Brazil, aligning with broader economic goals.

Shanghai to Buenos Aires via Auckland

The longest one-stop flight on the list measures 10,627 nautical miles (19,680 kilometers), connecting Shanghai to Buenos Aires with a stop in Auckland, operated by China Eastern Airlines. Using the Boeing 777-300ER, the route has a capacity of 318 passengers, including six first-class seats.

This service reflects China’s initiative to enhance relations with Argentina, while also tapping into the growing demand for travel between South America and Asia. With existing connections through LATAM and Qantas, this route aims to foster increased tourism and business exchanges.

In summary, these routes illustrate the ongoing complexity of international air travel, highlighting how airlines navigate challenges in connectivity and market demand. As 2025 approaches, travelers can look forward to a diverse range of long-haul options that facilitate global mobility.
