Morphology
The words 'thin' and 'air' evoke insubstantial, hardly perceptible space, so a learner who knows the constituents can infer a metaphorical sense of moving into nothingness. However, the exact idiomatic sense 'disappear completely without a trace' is an extended metaphorical use rather than a literal composition and depends on conventional usage, making the phrase only partially predictable to B1 learners.
Etymology
Into thin air creates the image of someone stepping into very thin air, as if the air is so empty there is nothing to hold or see them and they simply vanish. That's why it means 'to disappear completely'.
