As has been noted, a puzzle of two halves (N/S).
20d Cross country from the south, taking passport, say, around (2,1.4)
I-/A/-0-D. In a mood, I suppose, but why?

[dannyk13]

o(around) & oman(country)reversed indside ID(passport,say)

[mallyh]

I can see oman in id

[ceva]

old country from the south - OOMAN turned upside down
taking passport,say, round - put ID around to give - IN A MOOD

[dannyk13]

ceva, where do you get old from?

[Toorak]

Old is in the clue - ceva’s parsing is correct

[dannyk13]

So the poster missed part of the clue out.

[Toorak]

Yes

Grovelling apologies.. OP

[dannyk13]
