BA 2-4-1 voucher – can a booking be paid for with a foreign AMEX card?

[WorldFlyer]

The requirement to pay with an AMEX card still exists, right?

Can a reward flight using a BA 2-4-1 voucher be paid for with a foreign AMEX card?

Yes you need to pay with an Amex – you might need to try and see though with a foreign one. Sometimes a system will flag up immediately if it doesn’t accept a certain kind of card before you confirm payment.
