Snake that loves going on British Airways (3)
I believe the answer is:
boa
'snake' is the definition.
(boa is a kind of snake)
'loves going on british airways' is the wordplay.
'loves going' becomes 'o' (I can't explain this - if you can you should believe this answer much more).
'on' means one lot of letters goes inside another.
'british airways' becomes 'BA'.
'o' inserted inside 'ba' is 'BOA'.
'that' is the link.
Can you help me to learn more?
(Other definitions for boa that I've seen before include "Snake; fur" , "Fluffy scarf of feathers" , "Potential killer" , "strangler" , "Long, thin, feathery scarf" .)
