Unfortunately with all frequent flyer programs redemptions can represent really poor value for your hard-earned miles unless you can find a sweet spot. A good sweet spot is often long-haul business class (or even first class). Unfortunately these options aren't open to you with 30,000 miles.

Here is the TK webpage for redemption tables and some rules. I hope you can find something of interest:
