I did say "maybe," brunos! Also, I seem to recall from threads/posts some time ago that folks had to call the FB centre for this 'overdarft' option; however, I did it all on the website: When I first selected the award option and then clicked to proceed, a stark 'warning' message appeared informing me that I did not have sufficient miles in my account for the selected ticket.

So, I just let the 'feminine' side of my brain take over (), ignored the warning message and continued with complete disregard ... and it worked without a peep!

Much appreciated though, otherwise I would've had to wait well over a week to get the balance, and then the ticket may not have been available.
