with the exception of some A330s
QF has 18 A330-200's of which 7 have wifi fitted. Only the 10 without IFE screens in Economy were due to get wifi which means just 3 to fit. The remaining 8 wifi a fixed IFE screen at every seat aren't scheduled to get it. A 38% chance of wifi on an A332.
None of the A330-300's have it fitted as they were the international fleet. A 0% chance of wifi on an A333.
QF has 75 737's of which 3 aren't fitted - VH-VYD, VH-VYH and VH-XZB (the last was the test aircraft but had its dish removed). A 97% chance of wifi on 737 flights.
