PAL, 777's or 77W?

Philippine Airlines…do they all have B77W. You say on your flight tracker they have both 777 and the 77W. When I investigated, I only found 77W’s that they flew. This confused me on the FlightAware. Can somebody straighten me out about this?

Thanks.

Airfleets shows all -300’s so I would imagine it was ratty data

Philippine Airlines started to obtain them in 2012. Like I said, FlightAware says they use B777, but list only 1 B77W. I’m trying to learn about this, Thanks!
