High-flier's appearance embodying right pedigree (8)
I believe the answer is:
airliner
'high-flier's' is the definition.
'appearance embodying right pedigree' is the wordplay.
'appearance' becomes 'air' (I've seen this before).
'embodying' means one lot of letters goes inside another (to embody can mean to contain or include).
'right' becomes 'r' (common abbreviation).
'pedigree' becomes 'line' ('line' can be a synonym of 'pedigree').
'r'+'line'='rline'
'air' placed around 'rline' is 'AIRLINER'.
(Other definitions for airliner that I've seen before include "Commercial plane" , "Eg, Jumbo, Concorde" , "One going aloft" , "Large aircraft" , "Passenger plane" .)
