you would get allowances on top of that plus hdp (hourly duty pay) ,but very low since you do not reach high duty hour numbers on the freighter. per diem(or allowances) are been paid at the hotel in local currency. But rates are really low, e.g. Hong Kong around 60 Euros/day.( don't quote me on that, but it is really not a lot). expect around 400 Euros/month extra all in all. plus you have to pay tax on both ,hdp and allowances, as well !! the money as a based freight F/O with CX is really a joke, especially considering the gruesome patterns..
