Which of the following is the airport code for an international flight to Brazil?

The airport code B is GIG, which stands for Rio de Janeiro/Galeão International Airport in Brazil. This airport serves as one of the main international gateways to Brazil, facilitating flights from various international destinations. It is recognized for handling a significant volume of international traffic, providing essential connectivity for travelers heading to and from Brazil.

In contrast, the other airport codes listed do not relate to international flights to Brazil. UIO corresponds to Mariscal Sucre International Airport in Ecuador, RIC is for Richmond International Airport in Virginia, and SJT is the code for San Angelo Regional Airport in Texas. None of these airports are primary entry points to Brazil, making GIG the correct choice for the question regarding an international flight to Brazil.
