We did this also. But be careful. The vouchers could not be used for any flights we tried to get. Even 6 months out, nothing, nothing, nothing. In fact, I asked what IS available to any destination...NOTHING. We did have a nice meal. As for our luggage, a message was sent immediately and our bags went out on the next flight with us.
I won't do it again. I was so excited, and then so disappointed.
