My wife booked the flight the night before our scheduled flight. There's no point in booking early as the weather can change rapidly. The day before our flight it was pouring rain. The day of our flight was calm with crystal clear sky. Don't be cheap if this is your first ever helicopter ride. It was totally worth the money. The booking was simple. On our arrival at the check in, we were instructed on the safety procedures. We waited about 20 minutes before we were driven to the helipad 5 minutes away. We flew on the green helicopter. The flight was smooth and we felt safe the entire time. The pilot was informative and accommodating. The front seats had better views but the back seats were more spacious. We were fortunate to do a snow landing as the weather was clear and beautiful. We saw fox and franz Josef glaciers, mt Tasman, mt cook and many other landmarks. After a while, all the mountains and glaciers looked the same, stunningly beautiful. Overall, we had a fantastic time even though this was the most expensive part of our trip touring New Zealand.
