Qatar Airways is already known for providing an ultra-luxurious product, from an excellent first class on the A380 to business class on the Boeing 787 and Airbus A350. But for some passengers (those accustomed to flying around like this), a commercial flight just won’t cut it. It’s for these customers that the airline operates its Qatar Executive fleet, with planes ranging from small private jets to the (comparatively) gigantic Airbus A319.One such Executive fleet member is the G650, which looks a lot like Gulfstream’s off-the-shelf model, albeit with some much more posh appointments inside the cabin. I had a chance to visit the plane at the Farnborough Air Show, taking place this week just south of London.Flight Deck, Galley and Crew RestAfter stepping through the front door, you’ll first come to the cockpit.The cockpit on Qatar’s G650 looks to be identical to that on the base model, down to the placement of the cup holders.Qatar uses the G650ER — ER stands for Extended Range, and the plane can travel more than 8,500 miles without refueling, making it the longest-range business jet in the world.The cockpit is just about as advanced as they come — no surprise for a plane that’ll probably cost you some $70 million before modifications.There’s also a crew rest here, with a flat-bed seat, just like the stock version.Behind the crew rest, you’ll find the galley.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
