Ticket I have is not active (7)
I believe the answer is:
passive
'is not active' is the definition.
('passive' is the opposite to 'active')
'ticket i have' is the wordplay.
'ticket' becomes 'pass' (pass is a kind of ticket).
'i have' becomes 'I've' (contraction of 'I have').
'pass'+'ive'='PASSIVE'
(Other definitions for passive that I've seen before include "sort of voice" , "Docile" , "Inert, lethargic" , "Inactive or non-resistant" , "Submissive" .)
