Guess she might be a bit frustrated for a few reasons:
- QF don't have a great image in general; she might be disenchanted to sweep it to Qantas.
- If she sweeps to Velocity, she may be very confused on how to spend it (some unheard airlines, like Etihad).
- 135k points will at best get her a return in Y (on EY probably - best option, least YQ). She can't get a return in J for that.
- Redeeming mileage is very much maligned in public. We know how to do it; it's very difficult to convince other people that it can be done much easier than they believe (viz. impossible). Probably doesn't help, but I'm guessing she has no status.
Yes, we can tell people otherwise, but they content themselves however they want to use their points (or money for that matter).
The reactions we get from them when we tell them they could be flying Business or First class are not as obvious as you think; some people really don't care, even if you explain to them the "benefits".
