Anyone here know what will be happening with interline agreements once DL and NW merge?

I understand NW crew will be in DL uniforms soon, planes repainted this and that. Are we looking at a year plus for systems to be integrated?

I emailed our equivalent of a "pass bureau" today to check what the deal is, as we have an ID75 with DL and a ZED with NW. I asked will there be a collective agreement, will DL honour NW ZEDS etc etc, and all i got was "we have no update... keep checking online"... the idea of contacting either airline is beyond them, but i assume maybe this isn't even worked out yet?

Any info appreciated
