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

'air traveller' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.

'with some meagre belongings' is the wordplay.
'with' indicates the answer is hidden within the clue.
'GREBE' can be found hidden inside 'some meagre belongings'.

Can you help me to learn more?

(Other definitions for grebe that I've seen before include "Diver" , "Crested water-bird" , "I'll dive in" , "Diving waterbird" , "Flier" .)

I've seen this clue in the Sydney Morning Herald.
