The main reason that people jet into these resorts is convenience though - a skidoo ride from the arrivals hut to the hotel is about as convenient as it gets. The trouble with altiports is that they are limited in size and scope - if you see an A320 on approach it might be time to ski for cover.
A320's skim the ski slopes before touch down in Innsbruck
For real convenience Innsbruck airport offers international flights and ski lifts some 4 miles or so from the arrivals lounge. It is possible to be skiing in several locations around Innsbruck and watch your flight touching down on its in-bound leg. And the airport handles more than Cessna or variants - all short haul aircraft such as A320's and 737's form a regular procession in the flight corridor in the tight valley around Innsbruck. On the doorstep there are 3 credible ski areas, around 30 minutes or so are Seefeld or the 2000m+ resort of Kuhtai, whilst a little further is the mighty Stubai Glacier offering skiing to 3200m+. Mayrhofen and Kitzbuhel in one direction and Ischgl, Solden and St Anton in the other are all around an hour way.
Short or almost non-existent transfer times are a unique feature of Innsbruck and mean that groups spend time in the resort or on the slopes rather than an autobahn. This is a key factor when time pressure ensures that groups get the most out of the shortest time. And for final approach, there can be few more exhilarating sights than ski lifts climbing the mountainsides just out of the window.
