Arsonist disrupts air ferries (10)

I believe the answer is:

fireraiser

I'm a little stuck... Click here to teach me more about this clue!

'arsonist' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'disrupts air ferries' is the wordplay.
'disrupts' is an anagram indicator.
'air'+'ferries'='airferries'
'airferries' with letters rearranged gives 'FIRERAISER'.

Can you help me to learn more?

I've seen this clue in The Irish Independent.
