Do you depart from the capital Accra? On that day, flights transferring at Frankfurt are available from Accra to Nanjing. For the ticket price, you could contact some travel agencies in your country, since the ticket price on the international route is cheaper in the departure city.

Thank you for your response Mr Quin, but how do I get information about the flight and is it only on that day the flights will be available? I would be departing from Accra
