The known parameters:
I have classes to finish and papers to write up until about 28 May.
I am attending the centenary of the World Missionary Conference (which is another blog post in its own right) in Edinburgh from 2 to 6 June.
I need to get to Hobart (maybe with a quick laundry stop in Melbourne) by 14 or 15 June.
A travel agent suggests either Qantas+BA to Edinburgh or Emirates to Glasgow.
