road trip

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

'excursion of sorts' is the definition.
I know nothing about this answer so I can't judge whether this works.

'correct terminal of stansted airport' is the wordplay.
'correct' indicates an anagram.
'terminal of' indicates one should take the final letters (I've seen 'terminal' mean this (terminal refers to the end)).
The last letter of 'stansted' is 'd'.
'd'+'airport'='dairport'
'dairport' with letters rearranged gives 'ROAD TRIP'.

'for' acts as a link.

Can you help me to learn more?

(Another definition for road trip that I've seen is " movie - with 28a".)

I've seen this clue in The Guardian.
