Nicci,
The FAQ says
I made a booking using my destinations miles for travel after 31 December 2012, will this booking be protected?
Yes. Any flight bookings made using destinations miles will be honoured but changes or refunds are not permitted.
This is not the case, though, unless things have changed.
The original plan was that UK members could still REFUND existing redemptions after 31st December and get a refund of taxes AND miles. Members elsewhere would get a refund of the taxes but not the miles.
Can you please clarify?
