The Pakistan business magazine said that according to sources, the Ministry of Transport Department of Civil Aviation Yangon, Myanmar, in a notice asked PIA to settle all "pending dues" and if the airline was unable to pay, they would suspend all PIA's operations through its airspace, which may disturb all its scheduled flights to Kuala Lumpur, Hong Kong and Tokyo.
Sources said that MAA's payments were pending since 2012 when PIA flew over Myanmar's airspace in the months of April, May, June and July.
A spokesperson for PIA said the airline had received a notice of non-payment of 52,000 euros related to MAA payment due for the 2012 Haj season when PIA carried out charter operations for passengers from Afghanistan and Myanmar.
However, he said Myanmar airspace was not used for their normal scheduled flights, only during these particular charter flight operations.
The spokesperson explained that earlier PIA had a designated post for charter flights but this was removed a few years ago, hence the payments left unpaid since 2012.
He said he hoped the matter would be settled shortly and the 52,000 euros charge did not create a financial constraint for PIA.
