An aerosol delivery system has a fluid transfer article with a first region for holding an aerosol precursor and a second region to which the aerosol precursor is transferred from the first region. The second region includes a multiplicity of capillary tubes which extend from the first region to an end of the fluid-transfer article which is at or proximate a heating surface of a heater of the aerosol delivery system. The aerosol precursor passes along the capillary tubes and interacts thermally with the heater to form an aerosol from said aerosol precursor. The first region may be formed from a porous polymer material. An air-flow pathway extends along the heating surface with that air-flow pathway passing the ends of the capillary tubes. When the user sucks or inhales through the aerosol delivery system, air-flows through the air-flow pathway along and the heating surface, so that aerosol passes from the heater and/or the ends of the capillary tubes to the user in the air-flow.
