If you use The Helicopter Line for scenic flights around the South Island, expect departures from Queenstown and the West Coast to highlights like Milford Sound and the Franz Josef/Fox glacier areas, with options for glacier landings or transfers to remote sites. Tours are highly weather dependent, so book in advance but keep your schedule flexible for cancellations or rescheduling. There are strict safety, weight and health rules, so disclose required details when booking, arrive early to check in and follow the preflight briefing; luggage is limited so bring only essentials and a camera. Dress in layers and wear sturdy shoes for landings, and be prepared for premium pricing in exchange for quick access to otherwise remote landscapes.
