In 2024, a record 4.7 billion people are projected to travel by air—200 million more than in 2019.

While revenues surged to an estimated $896 billion globally last year, airlines face extremely slim margins. On average, they made just $5.44 in net profit per passenger in 2023. Today, the industry faces pressures from high interest rates, supply chain woes, and steep infrastructure costs.

This graphic shows the highest earning flight routes worldwide, based on data from OAG.

The Top Revenue-Generating Routes in 2023

Below, we show the airline routes with the highest revenues in the first half of 2023:

Route Airport Codes Revenue H1 2023
Sydney to Melbourne SYD-MEL $1.21B
New York to London JFK-LHR $1.15B
Riyadh to Jeddah RUH-JED $1.03B
Dubai to Riyadh DXB-RUH $990M
Los Angeles to New York LAX-JFK $801M
San Francisco to Newark SFO-EWR $722M
Newark to Los Angeles EWR-LAX $682M
Singapore to Sydney SIN-SYD $650M
New York to Paris JFK-CDG $647M
Perth to Melbourne PER-MEL $642M

As we can see, domestic flights comprised six of the 10 largest revenue-generating flights, with Sydney to Melbourne ranking first overall, at $1.21 billion.

In fact, this route is earning more than twice that of pre-pandemic levels, even as the number of passengers declined. The flight route is largely dominated by Qantas and Virgin Australia, with Qantas achieving record-breaking domestic earnings margins of 18% in the fiscal year ending in June 2023. Lower fuel costs and soaring ticket prices were key factors in driving revenues.

Furthermore, Qantas and Virgin Australia are major carriers for flights between Melbourne and Perth, another top-earning route.

New York to London, one of the busiest and most profitable routes globally, generated $1.15 billion in revenues, representing a 37% increase compared to the same period in 2019. Overall, the flight route had 3.88 million scheduled airline seats for the full year of 2023.

The highest revenue increase over this period was for flights from Dubai to Riyadh, with revenues surging 416% year-over-year. This two-hour flight, a highly lucrative route between major financial centers, is one of the busiest in the Middle East.
