Also please be aware as I have just noticed this myself. The exchange rate you get with the BA prepaid card is really not good. I can’t find this anywhere in the jargon but they certainly don’t give you the mastercard exchange rate as far as I can see.
Please correct me if I am wrong but using today as an example.
Mastercard GBP to EUR 1.8
BA prepaid GBP to EUR 1.5
It appears that this card is only good for use in the UK currently.
