In fact, they have started already and it is expected to run until June. During this tour the aircraft will visit 12 countries around the world. Of course the aircraft they will be using is a fully outfitted G500 and will demonstrate the cutting-edge and luxurious interior that this model can offer. It also gives Gulfstream an opportunity to test the interior in real-world operation just ahead of certification.
