Cork carrier using real screws? (3,6)

Ross

I believe the answer is:

aer lingus

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

'cork carrier' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'using real screws?' is the wordplay.
'screws?' is an anagram indicator (I've seen 'screwed' mean this).
'using'+'real'='usingreal'
'usingreal' anagrammed gives 'AER LINGUS'.

Can you help me to learn more?

(Another definition for aer lingus that I've seen is " Irish airline".)

I've seen this clue in the Sydney Morning Herald.
