I might stretch a point and go non one world to complete the Boeing set. There were a lot of them in Catania. I am after all stooping to fly Lufthansa for the JU52. Seems a bit extreme to do it on Qantas as I've no trips planned to Aus this year.
Also noticed with considerable glee this week that there is a heritage 'Finnish Airways' DC3 flying out of the wonderful but probably short lived Malmi airport in Helsinki so having a look at whether I can connect up with that at some point.
