Maintenance Human Performance
After diverting to ZZZ earlier in day for the same problem; we departed for ZZZ1. During climb we again experienced smoke in the cabin and multiple smoke detector activations. After the problem cleared as we expected we continued to ZZZ1. Everything returned to normal for the next 25 mins. As we arrived in ZZZ1 airspace we were put into holding. As we approached the hold; the cabin was again filling with smoke and smoke detectors activated. I was unwilling to hold and with ZZZ1 backed up; the only way to get priority was to declare an emergency. Again we believe no regulations were violated; but would like to be afforded protection in the safety program.
