Morning,

Trrying to book a ticket in First Residence between London and Abu Dhabi for two adults and one infant (0-2).

I know that you can use miles and cash if you don't have enough points so the 'normal' total is 219,836 for the two adults plus 10,910 for the infant and 75% of that is 173,060 and I have 174,000 but it won't let me book and says i don't have enough miles. If I remove the infant then I am able to move onto the next screen.

Does anyone know what I am doing wrong?

Is it 75% of the adult miles but 100% of the infant miles?

Do I need to transfer more miles over?

Thanks
