An air-cruise combines a short charter flight with a classic small-ship expedition. You typically fly from Punta Arenas, Chile, to King George Island in the South Shetland Islands, where you meet the expedition team near the airstrip. After a brief transfer to the shore, you board a Zodiac and head to your vessel—your comfortable base for the days ahead—then begin exploring the Antarctic Peninsula with guided landings and Zodiac cruises led by an expert team. Most itineraries include the return flight to Chile; others are hybrids that fly one way and sail the other.

Operationally, these programs have proven efficient over many seasons. Operators commonly use a BAe 146-200 (with about 70 seats) for the two-hour trip from Punta Arenas to King George Island, landing on a prepared runway near multiple international research bases.

Note that air-cruises bring trade-offs as well. Baggage limits are tighter and flights are weather-dependent, which can cause delays or itinerary adjustments. They save sea days and minimize motion exposure, but are generally shorter and at a higher per-day price, and a touch less “classic expedition” than sailing both ways.

The Drake Passage, the 500-mile-wide stretch of turbulent ocean between the southern tip of South America and Antarctica, is both an awe-inspiring and infamous part of the journey to the White Continent. Known as one of the roughest seas in the world, its unpredictable waters can alternate between the "Drake Lake," when seas are calm, and the "Drake Shake," when storms unleash powerful waves. For some adventurers, the Drake Passage is a rite of passage—a test of endurance and spirit that adds a sense of accomplishment to reaching the frozen wilderness. The experience of braving the open ocean, accompanied by albatrosses gliding above and the occasional whale breaking the surface, offers a visceral connection to the raw power of nature.

However, this treacherous crossing is not for everyone. The combination of high winds, towering swells, and a rolling ship can cause severe seasickness, even for seasoned travelers. For those who prefer smoother journeys, the prospect of spending two days navigating such volatile waters may outweigh the allure of adventure.
