Domestic  and  International

The word Domestic refers to anything that happens within one country.
When travel, business, or services take place inside national borders, they are considered domestic.
For example, a flight from Delhi to Mumbai or a trip from Kolkata to Goa is called a Domestic Flight or Domestic Trip.
Similarly, when a company sells products only within its own country, it is running a Domestic Business.
Domestic activities are generally simpler because the laws, language, and currency are the same across the nation.
They help strengthen the local economy and make it easier for citizens to connect and move freely within their own country.
