Another airline bites the dust of Venezuela’s worsening crisis, adding to the increasingly common sight of a near-empty tarmac at the Simón Bolívar airport serving Caracas.  Aeromexico, Mexico’s largest carrier, announced on Thursday it had halted flights to Venezuela.  In the latest signal of the dire state of an economy now ravaged by food riots, the Mexican carrier said in a statement that “after almost five years of having started operations between Mexico City and Caracas, it has decided to suspend its flights indefinitely due to the complex economic environment that rules in the country.” Foreign airlines have been struggling to repatriate money received from Venezuelan customers in local Bolívar currency due to exchange controls. Amid billions in unpaid bills, several other airlines have halted or reduced their operations to Caracas, including Air Canada, American Airlines, Alitalia and Latam, writes Andres Schipani.  Iata, the aviation industry trade body, recently said the socialist government was withholding $3.8bn from the carriers generated from ticket sales in Venezuela.
