Arrival and departure requirements in Punta Arenas, Chile

Travelers must arrive in Punta Arenas by 14:00 hrs (2:00 PM) on Day 1 of the itinerary of their trip. Travelers who miss this deadline will not be able to participate in the trip, and no refund will be extended. On the last day of the expedition, travelers are strongly encouraged to book flights departing in the late afternoon. We strongly recommend avoiding tight flight connections. We recommend booking a flexible airfare. It is also important to check visa requirements for your country for travel to Chile prior to your trip.

A number of national and international airlines land daily at Santiago’s airport. Two national airlines connect the capital of Chile and Punta Arenas with several daily flights. The distance between Santiago and Punta Arenas is about 3,000 km and a direct flight takes about 3 and half hours.

Punta Arenas is situated in the Chilean Patagonia where there are several border crossings between Chile and Argentina. Overland travel from El Calafate, Rio Gallegos, Rio Grande and Ushuaia is possible but takes a considerable amount of travel time. Punta Arenas can also be reached from Torres del Paine National Park (about 5 hours by car) and Puerto Natales (3 hours by car).

Arrival and departure requirements in Ushuaia, Argentina

A number of national and international airlines land daily at the Buenos Aires airport and several daily connections serve Ushuaia. The distance between Buenos Aires and Ushuaia is about 3,190 km and a direct flight takes about 3 hours and 40 minutes. The main Argentinean airline is Aerolineas Argentinas. Latam airline also operates in Argentina. Note that Buenos Aires has two airports that service Ushuaia; please double-check which airport your flight will leave from as they are on opposite sides of the city.

Travelers must arrive at the ship between 15:00 hrs (3:00 PM) and 16:00 hrs (4:00 PM). We strongly recommend avoiding tight flight connections. Travelers who miss this deadline will not be able to participate in the trip and no refund will be extended. It is also important to check visa requirements for your country for travel to Argentina and Chile prior to your trip.

Ushuaia lies on the southern shore of Tierra Del Fuego island, on the Beagle Channel, at the very end of the National Road n. 3 starting in Buenos Aires. This road links Ushuaia with other cities in Patagonia. Motor coach service between Ushuaia and Punta Arenas is available and takes approximately 10-12 hours, depending on border crossing.

Depending on your nationality, you may be required to pay a Reciprocity Fee to enter Argentina and/or to obtain an entry visa.

Participation Form

Travelers are required to review the My Expedition portal prior to departure. The participation form should be submitted no later than 120 days prior to departure.

Getting on and off the ship requires full mobility. You don’t need to be very agile but you do need to be able to walk and manage stairs independently, as well as to lift your legs over the pontoons of the Zodiacs to embark and disembark. Walks on the beach or further inland, with some low hill climbing, are available. You should be reasonably fit to be able to enjoy those activities but it will always be up to you how far you choose to walk. Physical activity will never be imposed and you can set your own pace.

In the Participation Form you will be asked to tell us all about your health problems, either past or present, including allergies, etc. This will allow our onboard doctor to be aware of the medical needs of each one of our passengers, and allow him or her to be better prepared.

Baggage Allowance

One of our most important travel tips for Antarctica is the weight of your bag. The maximum luggage weight allowed on flights to and from Antarctica is 20 kg (44 lbs.) per passenger, including hand luggage. For trips starting and ending in Punta Arenas, luggage exceeding this weight limit can be left in custody with Antarctica21. This luggage custody service is not available for Antarctica Express Air-Cruises starting in Ushuaia.


Antarctica21 requires participants to be adequately covered by medical insurance, including aero-medical evacuation from Antarctica. We also urge that all travelers be adequately covered by trip cancellation and interruption insurance.

Our ship has a small, well-equipped infirmary for the attention of minor medical problems and is under the care of a licensed medical doctor. Serious emergencies require evacuation to medical centres in South America that are better equipped, which requires a very costly air evacuation procedure. This is why we ask our passengers to have an insurance policy that covers emergency medical evacuation.

Contingency Plan

Flights to and from Antarctica operate based on weather conditions. While historically only a minority of flights have experienced a delay, you should be prepared for that possibility.

The “Important Information” and “Contingency Plan” sections of the Antarctica21 brochure detail the plan should unfavorable weather conditions impact the operation of the Antarctic flight. Travelers should review and understand these details.

Entry visas and Entry Fees

Another important travel tip for Antarctica and all of our destinations is for entry visas and fees. Travelers should check the entry requirements of the countries visited during their trip, based on their nationality. Antarctica Express AirCruises visit Argentina and Chile so the requirements of both countries should be considered.

Cuisine & Dietary Information

We are privileged to have a group of international chefs prepare a delicious selection of different cuisines throughout your trip. Wine, beer, juice and soft drinks served with lunch and dinner on board our ships are included, as well as coffee, tea, chocolate, cappuccino, water and snacks throughout the expedition. Note: beverages purchased at the ship’s bar as well as not-included beverage purchased in the dining room are at a charge.

Dietary requests must be made on the Participation Form you receive after your booking confirmation. This information will be passed along to our staff so they can accommodate your needs while on your voyage. Note: due to the nature of our expeditions and the kitchens onboard the ships, Kosher and vegan meals cannot be accommodated.

Personal Safety

Your safety is our main concern. You will be provided with a mandatory safety session before departing on your voyage. You will be shown where the life jackets are, as well as the safety boats in case of an emergency evacuation. During rough weather, do not walk in large, open areas and be sure to use handrails both outside and inside the vessel. Always use door handles and never hold doors by their frames, as a sudden movement may prove very dangerous. Always turn on the lights upon entering your cabin in case items have moved around. Use non-slip shoes when on deck, as it can be slippery at times.


Austral summer weather in Antarctica means mostly mild temperatures. You can expect cold, sunny days and brisk winds, which may turn into stormy weather and even a few snow flurries or snow. You should be prepared for quick changes in weather conditions. Below we offering more packing and travel tips for your expedition with us.

Our guide and driver were very good with their knowledge and were very helpful with our questions. It was a very pleasant visit that would have been impossible to do on our own. Hotels and restaurants were fantastic. The special places we got to go to, like the kitchens, were great. Enjoyed the entire trip!
