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

'those taking flight rested?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'exodus lie about' is the wordplay.
'exodus' becomes 'departure' (I've seen this before).
'lie about' becomes 'lounge' (to lounge is to lie or laze around).
'departure'+'lounge'='DEPARTURE LOUNGE'

'where' is the link.

Can you help me to learn more?

(Another definition for departure lounge that I've seen is " whence one heads heavenwards?".)

I've seen this clue in The Irish Times.
