Venezuela said on Tuesday that it would investigate the authorizations for two of the Miami-Caracas flights of American Airlines.

Venezuela's National Civil Aeronautic Institute said in a statement that it has opened an investigation to determine responsibility for the "irregular situation" of the two daily flights.

The two flights, 902 and 903, have been operated by American Airlines on its Miami-Caracas, Caracas-Miami route. The company suspended flight 903 on Monday, as it did not have authorization from Venezuela.

Venezuelan firms are only permitted to operate international flights in the United States, and internal air routes have always been shut away from them.
