I can confirm it works - just booked for October dates. ^
Thank you to the OP for pointing this out. Stunning fare and as it is a holiday I won't feel too bad about only getting 50% miles
Still 13060 miles (according to milecalc) at 50% = 6530 for £185 (inc credit card fee) is 2.8p (4.2c) / mile so not too bad for a place I have wanted to visit for a long time.
Thanks again zboub345 you are a :-:
