Seatguru lists three types of 747-400s in the CX fleet, with slightly different seating configurations.
Does anyone know how I can work out which type will be flying CX252?
I actually have a similar problem trying to work out which Airbus will be flying the CX163. Is it the A330-300 two or three class?
I'm sure there's an easy way to work this out, I just don't know what it is

I hope someone can help.
