Morphology
The sense 'broadcasting live' is related to combining 'on' (indicating an active/state) with 'air' viewed as the broadcast medium, so there is a recognizable compositional link. However, 'air' meaning 'the medium of broadcasting' is somewhat specialized/idiomatic and may not be obvious to a B1 learner who only knows the basic sense of 'air', so prior exposure is often needed.
Etymology
The phrase on air comes from early radio: when a studio sent voices out through the 'air' so people could hear them, the program was said to be on air. That's why on air means 'being broadcast live'.
