British Airways lays claim to the world’s single most profitable airline route, its New York JFK to London Heathrow jaunt. It generates $1.04 billion in revenue each year for the company, according to a new Forbes report relying on Official Airline Guide data.

The route is flown about 15 times daily and accounts for 6 percent of British Airways’ total revenue.

The other richest routes included:

Qantas, Melbourne (MEL) to Sydney (SYD): $855 million

Emirates, London Heathrow to Dubai (DXB): $819 million

Singapore Airlines, London Heathrow to Singapore (SIN): $710 million

American Airlines, Los Angeles (LAX) to New York (JFK): $698 million

United Airlines, San Francisco (SFO) to Newark (EWR): $688 million

Cathay Pacific Airways, Hong Kong (HKG) to London Heathrow: $632 million

Qatar Airways, London Heathrow to Doha (DOH): $553 million

Air Canada, Vancouver (YVR) to Toronto Pearson International Airport: $552 million

Singapore Airlines, Sydney to Singapore: $544 million

The only short-haul flight that made the list was Qantas’s Melbourne–Sydney service.

“All these findings signal that, despite the incursion of low-cost carriers into the airline marketplace on every continent, long-haul business travel remains the primary generator of revenue around the world,” Forbes noted.
