Yes the kite/golf bag is what we all use. Here is one model that easily fits a twin tip and three kites and more.
A few tricks: -don't roll your kites into tight balls.. loose lay them inside the bag to better fill the space -keep you total weight under 50 lb,, it's worth buying a small luggage scale -leave your kite bags at home to save weight.. Dakine makes very light kite bags for travel -take your fins off your board for travel
Chris nailed the points. I have been using a wilson golf bag for over a decade with no issue. I always throw a club in for good measure. Just got a new LF golf bag and is pretty slick. Opens coffin style so easy to set gear in place. Planning on simply using two golf bags this year to Baja.
