Long story short my wife and I have just over $200 each in Delta vouchers we need to use by December. We don't have anywhere we NEED to go or a date we NEED to travel on. Usually in this situation, we hop on Kayak and go to the Explore Map feature which shows you all destinations from your departure city. You can filter by date, location, etc. However, there is no filter for airline.

Since we have to fly Delta does anyone know of a tool that will easily let us explore every destination and time period so we can find the cheapest?

Thanks!
