Welcome Jomar! I went to the DCS World file downloads page and found a mission where you take off, fly through some waypoints, and land at another airport:

Another alternative is to try out multiplayer and jump on our Virtual Aerobatics server. It's a non-combat server where you can free fly where ever you want. Players of all skill levels fly on this server so there's no need to feel bad about your level of flying.
Again, welcome to the community and the key thing is to have fun!
