There's luxury travel and then there's super-luxury travel. And by any measure, touring the world on a specially outfitted private jet with 15 to 50 like-minded passengers, all on the same financial playing field, falls into the "ultra-luxe" category. For well-to-do, worldly travelers with destinations and experiences still on their bucket lists, joining a private jet tour is a popular way to efficiently explore the world in the lap of luxury. These all-inclusive trips can cost more than $100,000 per person. "But the level of care, the food and beverage offerings and the special amenities and white glove services are top of the line," said Becky Powell, president of Protravel International. "What really makes these journeys special is the ability to visit many exotic and off-the-beaten track destinations, stay in unique high-end accommodations and have access to curated, insider experiences." Sound like your kind of travel? Here are some private jet journeys to consider.

But the retired lawyer analyzed the offer and now he and his spouse are packing for their fourth Four Seasons private jet tour. "It's definitely an investment," said Petrina. "But you're given the opportunity to see remote places you wouldn't go on your own and in a very comfortable fashion." "We consider the airplane to be our 116th hotel and these trips an extension of our brand," said Javier Loureiro, director of guest experience on the Four Seasons jet.

In addition to fine dining, curated cultural events and an executive chef, a bonus on Abercrombie and Kent's around-the-world private jet tours is that they're hosted by company founder and co-chairman Geoffrey Kent. "Guests on these kinds of adventures take pleasure in meeting like-minded people with a shared curiosity about the world," said Kent. "We also find that once-in-a-lifetime trips, such as a private jet journey, tends to attract more solo travelers as well. I believe this is due to the unique destinations visited on these trips, as well as the length of the programs." Trips start at: $32, 495 (regional) and $160,000 per person (around the world)
