(In Feb 2011) A group of 5 of us booked and paid for a helicopter flight with snow landing,which was quite expensive but we thought it would be worth it. We were very excited. The helicopter flight was amazing, although to our shock the helicopter went back to base with no snow or glacier landing at all. When we asked, what about the snow landing, all we got told was that the weather conditions weren't right (too windy) for a landing.
What they didn't tell us upon booking is that a snow landing isn't guaranteed, even though you pay for one!
After a long argument with 2 of their staff, the manager eventually agreed to give us a minimal.
There was no information that snow landing isn't guranteed, they make it look like EVERYONE gets a snow landing, but this is not the case, and the price doesn't change if you don't land.

Early morning take off from Franz Joseph and treated like a VIP. Pilot very informative on way up the valley to the glacier.
Excellent photos from the helicopter.
Highlight was landing on the glacier. Again lots of photo oppertunities. Pilot took photos of each of us by the helicopter on the glacier.

A Trip not to be missed !!!!! I would do it again.

It is expensive so I can understand any hesitation but do it! It is worth every penny!
It is extremely weather dependent so I suggest the morning flight when the weather is typically the best. They take you on a short (about 7 minutes) flight and then land on the glacier. Your guide then takes your group on a walk around the glacier for a few hours. They really are careful about safety and carve out steps with an pick axe when necessary. The views are magnificent! When you stumble upon something like a cave, tunnel, or crevice the guide will check it out and ensure its safe before letting you climb through or on it. It is so fun! The guide on Fox Glacier was super cool and knowledgable.

Do it! Do it! Do it!
