A smoking article (2, 40, 50, 60) having a mouth end and a distal end, the smoking article (2, 40, 50, 60) comprises: a heat source (4); an aerosol-forming substrate (6) downstream of the heat source (4); at least one air inlet downstream of the aerosol-forming substrate (6); and an airflow pathway extending between the at least one air inlet and the mouth end of the smoking article (2, 40, 50 and 60). The airflow pathway comprises a first portion extending longitudinally upstream from the at least one air inlet towards the aerosol-forming substrate (6) and a second portion extending longitudinally downstream from the first portion to the mouth end of the smoking article (2, 40, 50, 60). |
