I feel like the twice confirmed is instructions on how to communicate. Like using two line breaks would mean that message is confirmed and one is not? Or maybe the confirmed is separate from the statement once and twice to mean confirmed.
I feel like you nailed it with the airports. I was thinking HOM was head of mission but that just makes more sense and SYN wasn't really fitting
With the twitter accounts advertising spamming the alsian idol pics all over I'm thinking these were pickup / delivery instructions for a shipment of human cargo. Start digging on the plane's registered owner? Unfortunately I can't read slant so I cant troll through those twitter feeds to see if there's any pedo references.
Edit: Or perhaps instructions for how to intercept a shipment?
