Actually, it's the other way around - Air Atlanta Icelandic wet-leased* the aircraft to Astral Aviation. It's unclear to me if the aircraft is still being operated for Astral, or if that's old livery which hasn't been painted over yet. Either way, it's an interesting flight from Milan to SXM.

Air Atlanta Icelandic has done some interesting charters over the years. They lease both freighters and passenger aircraft to a number of carriers and governments, as well as doing charters.

Iron Maiden fans may remember "Ed Force One" from the 2016 Book of Souls tour. (If heavy metal music makes your head hurt then don't click on this link) https://www.youtube.com/watch?v=nwpvoUYaR9U
