Morphology

jet + lag

The components 'jet' (aircraft) and 'lag' (delay) cue a travel-related timing mismatch, so learners can infer a delay or mismatch associated with flying. However the specific sense of bodily tiredness and sleep disturbance from crossing time zones (circadian disruption) is a specialized extension not fully predictable from the parts, so it is only partially transparent.

Etymology

Jet lag comes from fast airplane travel: a jet crosses many time zones and the lag is your body falling behind the new time, so you feel 'tired' and have 'sleep trouble'.
