I have always been told that pines do not air layer and the few times I have tried in the past would support that conclusion. I've found that juniper do air layer fairly well (60% success?)
That said, I always encourage experimentation so go for it, who knows you may be the one to teach us all something new. Please be sure to document your attempts and results with pics so you can share with us.
One thing to keep in mind, be sure to keep at least one large active branch below the air layer site, not having something to feed the roots is a guaranteed death sentence on any air layer, in my experience.
