Trip person using machine required to organise packages? (4,8)

I believe the answer is:

tour operator

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

'machine required to organise packages?' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'trip person' is the wordplay.
'trip' becomes 'tour' (a journey or expedition).
'person' becomes 'operator' (operator is a kind of person).
'tour'+'operator'='TOUR OPERATOR'

'using' is the link.

Can you help me to learn more?

(Other definitions for tour operator that I've seen before include "Company organising package holidays" , "Package holiday company" .)

I've seen this clue in The Irish Times.
