I mentioned this on one of the other threads in relation to my sister having her July flights cancelled that I can't understand why they are charging the fare difference, just waiving the change fee is ridiculous and that should be expected anyway when they do the cancellation. A refund would be her preferred option (I think she's going to try for a chargeback) but she still wants to do the trip in the future so would happily rebook for next year when things should be back to normal and they can keep her money, no hassle for them or her but now having got a good sale fare she's looking at potentially having to pay out who knows how much to rebook (SYD-LHR return in J). So short sighted and as you all say, doesn't bode well for their future bookings as they're now off the list for my whole family when doing the opposite journey annually.
