Innsbruck Kranebitten Airport (IATA: INN, ICAO: LOWI) is the largest airport in Tyrol in western Austria. It handles regional flights around the Alps, as well as seasonal international flights to other destinations. During the winter, activity increases significantly, due to the high number of skiers travelling to the region.
It is the main base of Welcome Air and Austrian Airlines' regional carrier Tyrolean Airways. The airport serves mostly mid-size and smaller jets and props, the airport does not see anything much bigger then the Boeing 767, which is private. Some airlines operate Boeing 757s out of LOWI, and connecting to major airport hubs, such as London's Heathrow International Airport. No commercial carrier operates from the United States to Innsbruck directly, which always connects via a European Airport. The approach is very difficult, even more so in the Winter, when the traffic soars.
The approach and descent is a very complicated process -- the Alps create vicious winds and currents, which the pilot has to deal with throughout the process. Because there are mountains all around, the plane usually circles the airport, enters a pattern, to kill both speed and altitude. The terminal is "shotgun" style, typically using air stairs to deboard/board passengers -- no jetways. Their are several de-icing trucks, which de-ice the airframe typically right before engine start, or before obtaining clearance to takeoff.
