What type of flights connect two destinations within the same country?

Domestic flights are those that operate within the boundaries of a single country, connecting various cities or regions without crossing international borders. This type of flight is essential for facilitating travel among residents and visitors alike within the same nation, serving destinations that might be significant for tourism or business.

International flights, on the other hand, involve travel between countries, so they do not fit the criteria of connecting two locations within the same country. Charter flights refer to non-scheduled flights that are typically booked for specific groups or events, but they can either be domestic or international and do not specifically imply a connection within one country. Low-cost flights refer to airlines that provide budget-friendly fares, which can operate domestically or internationally, but the term itself does not define the geographical scope of the flight.

Therefore, the definition and scope of domestic flights clearly indicate that they are designed specifically for connecting two places within the same country, making this the correct answer.
