scheduled flight
✈️ 航 = sail/navigate + 班 = scheduled group/shift
航 originally meant boats crossing water (舟 boat radical), now covers air and sea travel. 班 means a scheduled group or work shift. Together: a scheduled run — flight number or sailing.
班 — two jade 玨 + knife 刂 in the middle
班 originally depicted a knife (刂) dividing a pair of jade pieces (玨), showing the act of splitting jade between people. From this 'dividing' sense it came to mean 'distribute,' then 'a group formed by division,' giving modern meanings like class, team, or shift.
