Domestic airline [Real Tonga] just informed me that scheduled flight to OC-123 on 28th September has been canceled due to equipment trouble, and they are trying to reschedule. Rescheduled flight might be 1st October at the earliest...
This kind of thing happens sometime but I am still trying to push them to make it earlier.
I will keep you updated at this site however there is possibility that I may have to change destination to OC-169 or OC-064 or OC-191, or stay here in OC-049 to participate in Oceania Contest-Phone as my returning international flight to JA is fixed on 7th October 2016.
In case I can not fly to OC-123 this time, I will retry in next March or April if possible.
Thank you for your understanding.
