Manspreads when travelling (and more than once) (10)

I believe the answer is:

ampersands

I'm a little stuck... Click here to teach me more about this clue!

'more than once' is the definition.
I can't judge whether this defines the answer.

'manspreads when travelling' is the wordplay.
'when travelling' indicates anagramming the letters.
'manspreads' anagrammed gives 'AMPERSANDS'.

'and' is the link.

Can you help me to learn more?

(Another definition for ampersands that I've seen is " '&' symbols".)

I've seen this clue in The Guardian.
