OAG (ex Official Airline Guide, for those of us old enough to remember the fat paperback books) has published this interesting table which estimates the 10 highest yielding flights in the world (click to enlarge):
The richest route is the British Airways service from Heathrow to New York JFK which OAG estimates as being worth over $1 billion per year.
Intriguingly, based on OAG’s pricing date, this is not the most lucrative by hour of flying time. That award goes to the Emirates service from Heathrow to Dubai which generates $25,000 per hour. This is an ‘all A380’ route which is why the average revenue is so high.
There are three other Heathrow routes on the top 10 list – the Singapore Airlines service to Singapore ($700m per year), Cathay Pacific to Hong Kong ($631m) and Qatar Airways to Doha ($552m). Singapore Airlines is the only airline to feature twice on the list, with Sydney coming in at 10th place.
