Hey guys! I am proud enough to acknowledge you guys, that I have met Patrick Tsai, Former Vice Chairman of Cathay Pacific a few days ago.
He believes that there is a space for both the Sonic Cruiser, as well as the A 380 in Cathay Pacific's fleet. However, he is VERY certain that Cathay Pacific will continue to operate the B 747-400 at least for the next 25 years.
And their 19 B 744s will not be leaving the fleet anytime soon, provided that their oldest B 744 is just 10 years old. Still new I would say......
'They may even order the B 747-400ER in the future', he said.
Also, he stated that the A 340-600, B 777-300 ER etc(Which they may order in the future), will only be a supplement to their B 747-400s, but not a replacement for it. If CX is going to dump their B 747-400s anytime in the future, they wouldn't have done so much to upgrade them.
