Mountain transport in Switzerland with flies in (10)

I believe the answer is:

chairlifts

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

'mountain transport in switzerland with flies in' is the definition.
I can't judge whether this definition defines the answer.

'switzerland with flies in' is the wordplay.
'switzerland' becomes 'ch' (short for Confoederatio Helvetica, its Latin name).
'with' says to put letters next to each other.
'flies in' becomes 'airlifts' (airlifting is a kind of flying. I am not sure about the 'in' bit.).
'ch'+'airlifts'='CHAIRLIFTS'

Can you help me to learn more?
