 a substantially planar aerosol generating substrate;   at least one airflow channel extending along the substantially planar aerosol generating substrate; and   a wrapping member surrounding the substantially planar aerosol generating substrate and the at least one airflow channel.   
     
     
         2 . The aerosol generating article according to  claim 1 , wherein the aerosol generating article includes a distal end, a mouth end, a longitudinal axis extending between the mouth end and the distal end, and the at least one airflow channel extends in a first direction substantially parallel to the longitudinal axis. 
     
     
         3 . The aerosol generating article according to  claim 1 , wherein the at least one airflow channel comprises at least one groove formed in a surface of the substantially planar aerosol generating substrate. 
     
     
         4 . The aerosol generating article according to  claim 3 , wherein the aerosol generating substrate includes a plurality of said grooves arranged side by side to form a fluted surface. 
     
     
         5 . The aerosol generating article according to  claim 1 , wherein the at least one airflow channel comprises at least one airflow passage formed internally within the aerosol generating substrate. 
     
     
         6 . The aerosol generating article according to  claim 1 , wherein:
 the aerosol generating substrate comprises a plurality of aerosol generating strips extending in a first direction and arranged intermittently in a second direction perpendicular to the first direction; and   the at least one airflow channel comprises a plurality of airflow channels and one of said plurality of airflow channels is formed between each pair of intermittently arranged aerosol generating strips and in fluid communication with said pair of intermittently arranged aerosol generating strips.   
     
     
         7 . The aerosol generating article according to  claim 6 , wherein each of the plurality of aerosol generating strips comprises a same aerosol generating material. 
     
     
         8 . The aerosol generating article according to  claim 6 , wherein at least a first one of the plurality of aerosol generating strips comprises a first aerosol generating material and at least a second one of the plurality of aerosol generating strips comprises a second aerosol generating material that differs from the first aerosol generating material. 
     
     
         9 . The aerosol generating article according to  claim 6 , wherein at least one of the plurality of aerosol generating strips includes a flavourant. 
     
     
         10 .
