10,000 points in Y each way on JQ is a very good deal but so is 12,600 on QF. The 29,600 for J is decent, personally tend to do J when heading West and Y when heading East.This a really good offer from QF, 30% off for East Coast to WA in J great value. Even to Darwin in our Winter.
If you inebriate yourself enough in the Pub Lounge beforehand, even JQ could be tempting with it's low point requirement trips.
