To Antarctica and back in a day &ldquoImpossible,&rdquo we said, until we heard of Antarctica Sightseeing Flights&rsquo 12-hour trip to the South Magnetic Pole. The agency organises trips along 19 routes from five Australian cities &mdash Sydney, Melbourne, Perth, Adelaide and Brisbane &mdash on a Qantas 747-400ER aircraft. The southern-most con&shytinent comes into view three hours after take-off. The flights take you over landmarks such as the South Pole, Commonwealth Bay and the Ninnis and Mertz glaciers, flying as low as 10,000 feet, depending on weather conditions. On board, the cabin is divided into seven classes, experts describe the sights, and two comple&shymentary meals, snacks and bar services are provided. (from A$1,199-7,999 antarcticaflights.com.au)
