I've been playing with different CDPs, and accidentally discovering something very weird - rates and even availability are depending on chosen country of residence. For example, if you choose UK residency, there is no availability for any prestige collection in ORD on 31 of August. But there is plenty of availability for US residents. But if i choose UK residency, with my corporate code i've got some fantastic pre-paid rates, including one-way rentals LAS-LAX, LAX-SFO with unlimited miles and no one-way surcharge. But my corporate rate is not supposed to to have pre-paid rates.

Have anybody encountered such things before ?
