As far as I know BA's most profitable routes are it's LHR - Johannesburg and LHR - Capetown routes. Kinda surprising I know - with the competition from VS and SAA.
I've also heard in transatlantic terms, one of CO's most profitable routes is TLV. At the moment they fly daily EWR - TLV, and there are plans to increase that to twice daily next year.
Just wondering whta's EIs most profitable route?
hope it's a help,
