I have my fiance waitlisted to U/g using UCs on Oct 14 QF94. I have been watching this flight for U availability and other than Fridays and weekends when the J load is higher, U usually opens up 3 days or so before the flight. Now coming up to Oct 14 I check today and all of a sudden none of the QF94 flights on upcoming days incl Oct 14 have any U (even Oct 9) even though for most they show J9 D9. Why is QF not releasing what is clearly available J seats to U? And why has this only started happening in the last week (eg Oct 7 QF 94 had U released).
