It's true: the fourth-smallest country in Europe has no airports. In fact, the Principality of Liechtenstein lacks both a harbour and a shoreline, making it a doubly landlocked country. That is, it is landlocked, and the nations bordering it are also landlocked. The nearest airport is St. Gallen–Altenrhein Airport in Switzerland, however there are other options for getting to Vaduz, including train, bus, and vehicle.
