Double-decker bus
In Argentina, double-decker buses are the second most widely used means of transport for long distance trips in Argentina, only after aeroplanes. Argentina is a very large country, and most trips take a large amount of time, so long-distance bus companies offer high quality services which include waiters, hot and cold beverages and regular food. For very long-distance trips, most companies offer buses with large seats that can be pulled back and be shaped into a bed. Double-decker buses are also used by tourists in Buenos Aires where they're used in city-tours.
