Girdwood is a city in Alaska located about 30 miles south of Anchorage along the Seward Highway and is home Alaska's largest ski area the Alyeska Resort which was home to the 2007 US alpine Ski championships.
Although Girdwood does have a small airport it is primarily used as a base of operations for local heli-skiing guide companies  and given the length of the runway it is suitable for only small prop planes; thus ruling out air travel as a method for getting to town. This means almost everyone who comes to Girdwood including Alaskan locals come in by car or shuttle. For those originating farther a field the closest major airport is the Ted Stevens International Airport in Anchorage. The airport is served by most major airlines and can be reached on non-spot flights from such major US cities as Denver, Seattle, and San Francisco. If not renting a car prior to arrival one should arrange shuttle travel to Girdwood and have them meet you at the airport.
Currently there is not a pubic transportation system in Girdwood although the Alyeska Resort Hotel does provide and hourly shuttle from the hotel for guests and is in discussion with the City of Anchorage for the permits to jointly operate a shuttle with the town of Girdwood. Given this situation, the tiny nature of the town and that a shuttle is an easy option from Anchorage there is no desperate need for a rental car.
