Airline carried out check on boarding passengers? (9)
I believe the answer is:
barricade
'check on boarding passengers?' is the definition.
The definition and answer can be both related to competing as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
'airline carried out' is the wordplay.
'airline' becomes 'BA' (British Airways).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'carried' anagrammed gives 'rricade'.
'ba'+'rricade'='BARRICADE'
Can you help me to learn more?
(Other definitions for barricade that I've seen before include "Fortification, barrier" , "Barrier, to block a street perhaps" , "Erected defence" , "Improvised obstruction" , "Block progress" .)
