Private-jet expeditions are the latest watchword among travelers who want to see it all.

Our next destination, just a few hours away, was Bogota, Colombia.

It would be the final stop of a 13-day expedition through South America.

A few days before that, I had rubbed elbows with gauchos in the wine country of Argentina.

Two days prior, I had crouched beside hundred-year-old Galapagos tortoises in the hills of Ecuadors Santa Cruz Island.

It was, to say the least, no ordinary trip.

My own, last October, was shorter, if more focused.

A typical commercial version of this jet might have a crew of seven and 196 passengers.

The interior was arranged in business-class style, with two-by-two Italian leather seats that can lie fully flat.

Upon arrival, we were often met by an escort, who helped us bypass any lines.

Wherever possible, the necessary paperwork immigration forms and the like was handled on our behalf.

TCS also organizes activities at every stop.

The companys experience really came to the fore when things went sideways.

By the time we landed in Bolivia, everything was running seamlessly.

Soon enough, we arrived atPortal,a monumental sculpture built from 5,000 salt bricks.

Sharing Bolivia with travelers from around the world is deeply personal, Mariano told me later.

As far as Im concerned, they most certainly succeeded.
