I have 5 Virgin accounts. I accepted the 10K on my real account because the miles will accumulate on that account. As far as the others, does it make sense to take the $100 instead because I can definitely use it for a very cheap flight, but if I take 10K, it's hard because most awards start at 12.5K, and the miles will never accumulate. On the other hand, even if I take miles, I can use 10K for a 50% discount of $100 on a paid flight. Anyone have any insight?
