<bot>: The cheapest ways to get to the closest international airport depend on your location and the transportation options available. Common options include public transit, ridesharing, carpooling, and taxi services. For example, if taking public transit, you could look up the closest bus or train route to the airport and purchase a ticket online. If you opt for carpooling, you could try using a ridesharing or carpooling app such as Lyft or Uber. You could also explore carpooling services such as Zimride or Carpool World. Finally, you could consider taking a taxi to the airport, which may cost more than other options but can be a fast and convenient way of getting to the airport.
