Hotshot packing current luggage for flights (10)

I believe the answer is:

staircases

'flights' is the definition.
(I've seen this before)

'hotshot packing current luggage' is the wordplay.
'hotshot' becomes 'star' (synonyms).
'packing' is an insertion indicator (some letters are packed inside).
'current' becomes 'I' (physics symbol).
'luggage' becomes 'cases' (I've seen this before).
'star' enclosing 'i' is 'stair'.
'stair'+'cases'='STAIRCASES'

'for' acts as a link.

(Another definition for staircases that I've seen is " flights".)

I've seen this clue in The Guardian.
