Unlike airplanes, airships are lighter-than-air vehicles—similar to blimps but faster. Airships wouldn't need airports for takeoff and landing, allowing them a wider range of places to pick up and drop off passengers.
Airships also have the potential to be less damaging to the environment than airplanes and cars, although this hasn't been proven yet.
Here's a simulation of what it would look like:
Unfortunately, airships are unlikely to be a budget travel option, at least not at first. Current designs require costly equipment, and Aeros is pitching their first airship as a vehicle to transport executives, most likely between the U.S. and Europe.
