Hoping I don't get a lazy agent in this case. Have two separate scenarios
OSL-WAW-DUB on LOT, and DUB-FRA on LH. Since its all inter-EU (but not schengen) I hope they can check bag through and I can use mobile boarding pass of sorts. If not I'm preparing for a recheck in DUB since two PNRs.
I also realized that I have a nice run of FRA-MUC-LHR on LH, LHR-YUL-SFO on AC, and SFO-EWR on United. Is it possible to do interlines on THREE carriers?

Star Gold so free bag. Would be one heck of a souvenir bag tag - current record is 4 codes on a tag.
Now that I've been thinking about it... there are a lot of *A to *A trips I have coming up on different PNRs, this would be pretty cool - do you have to present both tickets to Agent at origin?
