I guess that they will use their other 2 aircraft to operate the remainder of the summer season. Then it is the quiet time in the Irish charter market, so I guess they will look doing some other ACMI business. Maybe Ryanair again or Easyjet, they have been operating for EZY recently.
Looks like good news with the 2 aircraft going to Indonesia, rather than sitting around Europe when it is quiet. Don't other charter airlines send aircraft to the far eastand north america for the winter?
Their AOC is valid to 23 Dec, and the licence that you refer to is the one issued by the civil aviation regulator
My 2 cents
