Note: We have been having customer service issues with Jetsmarter so we can’t recommend their services at this time.Gulfstream’s G650 isn’t the world’s largest private jet, but it is one of the fastest (cruising at up to 610 mph) — and most luxurious. While private jet ownership is out of reach of most TPG readers — a G650 will run you a cool $66 million — services like JetSmarter make a flight on this plane (and others like it) much more affordable.With these new charter options now available, I decided to visit Gulfstream’s booth at the Farnborough Air Show to take a tour of the manufacturer’s flagship jet. Note that this particular aircraft offered a standard configuration — the interior can be customized as you see fit, with an option to add or remove seats, add an in-flight shower and more.Flight Deck, Galley and Crew RestThe G650’s flight deck is just as modern as one you’d find on a commercial airliner, as you’d expect from a plane in this price range.The cabin is very high tech as well, both when it comes to passenger amenities and flight attendant controls.There’s even a luxurious crew rest, with a slide-out wall and a flat-bed leather seat.There’s a decent-size galley with an oven and espresso machine.There’s even a full-size kitchen sink!Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

The forward lav is fairly basic.While the rear lavatory is a bit more luxurious.The rear lav also provides access to the luggage compartment, which is located at the far back of the plane.There’s plenty of storage at the rear for passenger and crew bags — there’s no need to bother with overhead bins here.Bottom LineGulfstream’s G650 is a magnificent aircraft, but it’s also tremendously expensive.It’s clear that Gulfstream takes a lot of pride in its aircraft — the company kept its planes spotless during the Farnborough Air Show, and made an effort to keep potential customers happy (I had to deplane when a prospective buyer dropped by the G650).If you’re in the market for a plane (either to charter or own) that can hold up to 18 passengers and can travel up to 8,000 miles without stopping to refuel, you’re not going to do much better than this.See below for more from Farnborough 2016:Bumping into British PM David Cameron at the Farnborough Air ShowTour Boeing’s Brand New 737 MAX, Launching with Southwest in 2017Inside the E2, Embraer’s Next-Gen Regional JetTouring the Bombardier CSeries Jet, Now Flying with SwissWatch an F-35 Fighter Jet Hover at the 2016 Farnborough Air ShowCheck Out Qatar’s All-Business-Class Airbus A319 JetInside the Gulfstream G650, One of the World’s Fastest Business JetsExplore Qatar Airways’ Incredible Gulfstream G650 Private JetTake a Look Inside Honda’s $4.5 Million Private JetComparing Economy Seat Pitch, from 29 to 34 InchesHave you flown on a Gulfstream G650?
