Well actually.. you just happened to ask in a really bad time for them, as the Teen Titans title is.. sure doing something with them. Jason has become some sort of mentor for Damian, as seen in Teen Titans #22, but the upcoming annual teased a fight between them, as apparently Jason.. betrayed him? We will see. (though i personally wouldn’t hold my breath because this Teen Titans run is an absolute set back for Damian’s character)

That aside, generally they seemed to be in good terms, Jason acting like an annoying older brother to Damian (and in return Damian acting like a bratty younger brother)

Red Hood and the Outlaws #17

Detective Comics #968

Batman #16 

Batman and the Signal #3

then before rebirth, they teamed up in Batman Inc #4, which is still canon, as wingman has been mentioned again in red hood: outlaw

and had an altercation in Batman and Robin #11

but Jason reminds it.. fondly (as shown in Batman and Robin #33)
