Will be travelling on CX later this yr from BNE to TPE via HKG. I tried to check the fare online via CX booking system, and have noticed that online seat allocation is possible at the same time with booking. 3 sectors will be on A330-300 while one whill be on B747. Any suggestions on best Y seats on the aircrafts? I have been looking at 30A/K on airbus and another front cabin bulkhead in B747. This is advisable? Are bulkheads much better than other seats in the cabin?
