Asiana USA Routes
Japan gets Tokyo four times daily at 1000, 1130, 1710 and 1850. Here, Asiana put on pretty much any plane that is spare, so you can end up with anything from a 767 to a 777, 747 or even an A330.

Asiana Asian Routes
Shanghai is four times a day, with the 0940 getting the dreaded 747 combi (with First), a 777 on the 1050, A330 on the 1410 and A321 on the 1515. Beijing gets an equally mixed bunch of equipment on the four daily flights, at 0840, 0950, 1320 and 1515.

There is a twice daily flight to Hong Kong, at 0920 and 1945, but equipment on this can be a random bunch of 777s, 767, and both types of the 747, with even the horrible Combi making an appearance.
There is just one flight a day to Australia. A 777 leaves Seoul at 1950, landing in Sydney at 0800 the next day, then with a fast turn around it leaves again at 0930, to get into Seoul at 1810. Annoying, this doesn't connect with any of the European flights on the way back, leaving you with an overnight stop over. See in the hints and tips section for details of making this bearable.
