We present radiation-driven wind models for Luminous Blue Variables and predictions of their mass-loss rates. A comparison between our theoretical results and observations of AG Car shows that the variable mass loss behaviour of LBVs is due the recombination/ionisation of Fe iv/iii and Fe iii/ii. A present-day mass of 35 M⊙ for AG Car is derived.
