Appropriate some of the cheap tickets (3)
I believe the answer is:
apt
'appropriate' is the definition.
(synonyms)
'some of the cheap tickets' is the wordplay.
'some of' indicates the answer is hidden within the clue.
'APT' can be found hidden inside 'cheap tickets'.
(Other definitions for apt that I've seen before include "Proper" , "To the point" , "Apposite, appropriate" , "Suitable or likely" , "Tap (anag.)" .)
