Almost any time there are separate tickets and separate PNRs, I would assume unless I specifically know otherwise that I will need to check in twice. In fact, even if the rules say that through check in is allowed, I would be skeptical about whether a random DL agent will know this and/or be able to do it on the day of travel.
