'with a ticket for it perhaps our' is the definition.
I can't judge whether this definition defines the answer.

'airmen flew endlessly' is the wordplay.
'airmen' becomes 'RAF' (Royal Air Force).
'endlessly' means to remove the last letter.
'flew' with its final letter removed is 'fle'.
'raf'+'fle'='RAFFLE'

Can you help me to learn more?

(Other definitions for raffle that I've seen before include "charity event" , "Sweepstake" , "Fund-raising draw" , "Lottery with articles as prizes" , "Lotto" .)
