Stuck on last two clues this week:
4d Order first class travel of a type (8)
-A-I---L
15a Chum (4)
--S-
(All across clues are words that mean nonsense)
Thinking this might be Fish (but not sure I can think of a context of fish meaning nonsense - "oh fish!" maybe a?!)
Any help gratefully received.
Cheers,
Paul.
