Interesting that it jumped four QR A359s: MSN 100, MSN 106, MSN 114 and MSN 126.
I don’t try to understand what is going on with QR’s frames. I hope someone in Airbus does !! I think MSN 100 was expected to be one of the original 4 cancellations. The hope was that now the cancellations would be just orders rather than anything that had been built.
