I'm fully aware of the scale on which operations plan ahead. That is why I said "One can only hope with forward planning, next year's schedule sees more A321s."
I may be giving them the benefit of doubt that domestic CE has caught them on the hop; but it is certainly working for them.
Whilst I still hold an element of grudge against them for the Terminal 3 debacle, I would still rather see whatever connectivity there is go via our national carrier than, say KLM...
