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

'one incorporated airline?' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'landed like' is the wordplay.
'landed' becomes 'alit' (alight can mean to land).
'like' becomes 'alia' (I can't justify this - if you can you should believe this answer much more).
'alit'+'alia'='ALITALIA'
