hopeful

'desirous' is the definition.
(thesaurus)

'a flight on fantastic fuel' is the wordplay.
'a flight on' becomes 'hop' (I can't justify this - if you can you should give a lot more credence to this answer).
'fantastic' indicates an anagram.
'fuel' anagrammed gives 'eful'.
'hop'+'eful'='HOPEFUL'

'to make' is the link.

Can you help me to learn more?

(Other definitions for hopeful that I've seen before include "One wishing to succeed" , "Promising success" , "Prospect" , "Wannabe" , "Optimistic, expectant" .)

I've seen this clue in the Evening Standard.
