A340's are technically the same size as a 330 - with a different seat config to give about 20 more seats in a 3 class, but less premium heavy, config. Surprisingly, the 77H only has 275 seats, so that would've only given another 33 seats above the 33G normally used as well.

A 77G (340 new seats) probably would've been the best replacement, but CX doesn't have extra 777s lying around like they do the underutilized 747s.
