So what exactly is prompting this change from regional 777's to 74As and 33Bs? If it were just on the HKG-BOM (non-stop and via BKK) route, I would have guessed it was increasing competition with the Indian carriers, notably 9W. But both the upgraded routes continue onwards to DXB. Is there something about the HKG-DXB market or the BOM-DXB market (on CX) that has changed all of a sudden that's reason enough to upgrade equipment? Just curious, that's all.
