Unrestrained, like Brazil-NY flight? (7)
I believe the answer is:
riotous
'unrestrained' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for riotous that I've seen before include "Wild, uncontrolled" , "Artificial fabric" , "Involving wild behaviour" , "Wild, disorderly" , "Unruly U rebellious" .)
