For example, Virgin points might be used for a partner flight to Japan, but taxes and carrier surcharges can be substantial and award rates can devalue. Award-seat availability was not checked. Transfers are generally irreversible: confirm an actual bookable award and the current account terms before moving points, and avoid speculative transfers.
