I am looking to book LHR - AUH with miles. My miles balance with Etihad is currently 202. I will transfer points from Amex if I decide to book with miles. However, when I try to get an idea of how many miles the flight will cost I can't proceed past the outbound as the website states I don't have enough miles, which I am aware of. I have boked miles flights before on Etihad by making a dummy booking so I know how many points to transfer from Amex. So how do I do that now? I need to know how many miles the flight will cost before I commit and before I transfer the Amex points???
