Spain's air upset some capital people (9)

I believe the answer is:

parisians

'people' is the definition.
The answer is an example.

'spain's air upset some capital' is the wordplay.
'upset' indicates an anagram.
'capital' suggests taking the first letters.
The initial letter of 'some' is 's'.
'spain'+'air'='spainair'
'spainair' anagrammed gives 'parisian'.
'parisian'+'s'='PARISIANS'
