Interesting! It may show a change... or maybe it shows that persistence pays off (literally in this case)
They canceled one of my upcoming flights today (DUS-KLX, a re-booked economy-coupon-upgraded flight that had previously already been canceled in May and moved to November). Good thing that I somewhat expected that to happen and with last weeks sales already booked an Z-class fare to ATH instead. Funny thing is that the (now canceled) Economy fare was actually about the same price as new Business class fare that I booked last week.
On the one hand it would be good to get a refund on that flight, as I still have a bunch of other vouchers with other airlines. On the other hand it will likely be a huge fight...and as long as A3 doesn't go belly-up I'd most likely spend/use it at some point next year anyway...
