People in Provo are great. Very friendly. Provo air center is reliable and one of the best FBO's in the Carib along with La Romana DR. My company doesn't use FLTPLAN.COM for int'l ops, so I called a briefer. Pretty straight forward. If you're unfamiliar with int'l flight plans, get your hands on an int'l flight plan form before calling the briefer as there is some additional info they require (emergency equip, life rafts ect...). Enjoy the flight, the approach is pretty scenic. Cool place to fly into.
