Reply To: BA charging full price for infant on Barclays upgrade voucher booking

[AndrewT]

The rules are (not) clear – infant pays 10% of the adult fare.

When using a voucher is that 10% of the normal adult fare or 10% of the fare paid by the adult on the booking? In the case of a cash fare where the fare is obviously variable it is effectively the latter, so certainly a good argument to try again to see if you can find someone to apply the same approach for a voucher ‘fare’.
