To me, this news serves to reinforce the CX market strategy of beating them with frequency and product. You will not beat HKA A380s on seat economics (even if we buy A380s ourselves), but you can keep the product offering superior in terms of passenger experience, convenient connections, and frequency for time sensitive travellers. That combined with a cargo hold full of revenue should enable CX to remain competitive in response to this challenge. Reference our competitive position on the DXB route against Emirates' A380s.
The worst thing CX could do would be to run a parallel A380 on the same routes as HKA. We would do so at a cost disadvantage, flood the market with seats, and simultaneously destroy cargo revenue and frequency for our business pax. How would that make any sense?
Stay quick, nimble, and better than the adversary. Don't stoop to their level! Now let the floggings begin...
