Luxury hotel chain Four Seasons is pushing the envelope by launching a custom-designed, fully-branded private jet that will whisk passengers to exotic locations all around the world on bespoke journeys. 

The entirely retro-fitted Boeing 757 will, of course, feature super-luxe interiors with individually handcrafted leather flatbed seats. You'll also get to enjoy global in-flight Wi-Fi and top-notch service from  Four Seasons in-flight staff, a dedicated on-board concierge, as well as local Four Seasons concierges at each destination. 

Some of the itineraries in the works include a 24-day Around the World trip (February 2015), which will take you to a total of nine destinations, including Bora Bora, India and Australia. There's also Backstage with the Arts (April 2015)—you'll get to experience some of Europe's most gorgeous museums and the Estates Theatre in Paris, among other landmarks. Each journey, which accommodates up to 52 passengers, includes air travel and ground transportation, planned excursions, meals and accommodation at Four Seasons properties. 

Obviously, prices are sky-high. Fares for the Around the World itinerary start from a whopping USD119,000 (S$149,452) per person. Plus, the jet (along with accompanying staff and crew) may also be privately chartered. Now, how's that for extravagance?
