I think the interesting points around the new CX numbers are the fact:
-the numbers are non sequential (with not CX216/217 etc), the only Euro point to see this.
-MAN is the only 'new batch' of Euro routes to see this change into the 'legacy' CX2** numbers, away from the CX3** numbers (one wonders if a new Euro route is being launched that needs the MAN flight numbers?
-As said, these new flight numbers could fit in a 2 daily sequence. Maybe 8 or even 10 weekly to begin with?
