packs in

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

'gives up' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'prepares to travel home' is the wordplay.
'prepares to travel' becomes 'packs' (I've seen this in another clue).
'home' becomes 'in' (to be in is to be (at) home).
'packs'+'in'='PACKS IN'

'and' acts as a link.

Can you help me to learn more?

(Another definition for packs in that I've seen is " Stops".)

I've seen this clue in The Guardian.
