The has been a massive hike in landing charges for international airlines flying to Juba.
The fees have been described as outrageous by Airlines.
4.000 US Dollars per aircraft landing and parking fees are now US Dollars 420.
Airport tax for international passengers, according to the source passing the information from Juba say it is now 122 US Dollars.
The South Sudanese government, broke since the outbreak of civil strife and the failure of the Addis Ababa peace accord, has been desperately trying to raise revenues.
Among the measure a 10.000 US Dollar work permit fee for professional foreign employees such as bank managers, also described at the time by the private sectors from across Eastern Africa as counterproductive as it would only lead to the rapid withdrawal of companies from South Sudan, which will cause the economy to fall further.
The measures taken to raise aviation fees is likely to further drive fares to Juba up and some airlines are expected to reduce flights in response to the new charges which are effective with immediate effect.
