Crossword Genius

She may provide flying courses (10)

Ross

I believe the answer is:

stewardess

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

'she may' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.

'flying courses' is the wordplay.
I cannot quite see how this works, but
'courses' could be 'ss' (symbol for south - a course or direction - twice) and 'ss' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

'provide' acts as a link.

Can you help me to learn more?

(Other definitions for stewardess that I've seen before include "Aircraft attendant" , "Female flight attendant" , "working woman" .)
