Based in Singapore and flying with other Oneworld partners, the flight calculator was invaluable for checking on tier point earnings. It is no longer there, I imagine because Avios for BA is now based on spend rather than distance, but seems a bit churlish to remove it for all the other carriers.

Anyone know if its gone for good, or is this just a temporary thing?

Edit to add that it still seems live if you type on the URL:
