With this thread in mind, I thought I'd try a little experiment, on availability of economy seats to London. I picked 3 midweek dates later this year to see if I could get seats from MEL to London, on different airlines (except VS where the only option is SYD to London). The airlines/programmes chosen were QF/QFF, SQ/KrisFlyer, NZ/Airpoints. I have also asked Velocity call centre for availability for travel on MH using velocity points on 15 May (waiting to hear back). MH & NZ were assessed using return availability two weeks as oneway redemptions very expensive on NZ, and not available on MH.
For NZ, the Airpoints programme works on any seat available at a commercial fare - so of course availability is fine, but for this exercise as I have an Altitude credit card, I wanted to see if the rates were comparable to QF FF points, and 160 Altitude pt = 1 Airpoints Dollar = 80 QF FF points.
Dates chosen were 15 May, 15 Jul & 15 Sep.
Results:
15 May - QF:nil, SQ:3 options, NZ:available for extra 11% of points, but on 16 May available*, VS - 1 option.
15 July - QF: nil, VS:nil; SQ:1 option, NZ:available for extra 45% of points
15 Sep: - QF:nil, VS:nil, SQ:1 option, NZ:available*
I could not find any availability on QF in Y from at all in from May through Sep, but good availability in October on Mon/Tue/Wed.
I am a PPS member with SQ, I don't know if that influences availability on them. However also a WP on QF and that used to have better availability (but I note that since they've been selling Y+, all awards book to X class - does that mean the T class inventories have gone?)
Make of this what you will!
* noting that cost was equivalent to 130,000 QF FF points return, comparable to the 128,000 for QF award.
