Mrs. CJ and I each have $300 vdb vouchers we received earlier in the year.

We would like to use these to on a vacation of some sort - we've been looking caribbean. However, NWA.com shows that NW flies to these destinations on code-shares (I'm assuming CO).

Problem is when we check fares, we get either "we don't fly here" or some routing on KLM through AMS that is $10,000+

Do I need to call, or won't NW tickets these routes even though they claim to fly there on code-shares?

thanks......
