Southwest Airlines Decorated planes

I have seen some southwest decorated planes in the air and on the internet (i.e. the shamu plane, the texas plane). I live near philly. Is there any way to find out on the internet when these decorated planes will fly to philly again? Are these planes given random routes?

Each of the special aircraft are routed just like any other aircraft in Southwest’s fleet so it isn’t possible to determine when any given aircraft will be in PHL.

they are at www.twitter.com/southwestair

they release where their 4 Wi-Fi planes are to be every weekday
see if that works for the special liverys as well.

The original poster was asking about the special color scheme aircraft, not wi-fi enabled aircraft.
