The skies over Venezuela are a little emptier at the moment, after major airlines suspended or scaled back flights because the government owes 24 of them $4bn.

Tight currency controls mean that all ticket sales have to be done in the local bolivar, and go through a tightly controlled government account.

But the national economy is crashing, so the government does not have enough cash to exchange the money and pay the airlines back.
