“Under Venezuela’s foreign exchange controls, access to dollars is tightly restricted. International airlines serving the country are currently owed up to $2.6 billion in dollars for bolivars that they have turned in to Venezuela’s Cadivi foreign exchange agency. Air Europa is owed upwards of $160 million, it said. A company director is flying to Caracas on Monday to meet with the country’s foreign exchange agency to discuss the problem, the airline said Friday. The company operates its Madrid-Caracas-Madrid route six times a week. Most other international airlines are taking other steps to limit their exposure to Venezuelan bolivars, which aren’t convertible outside the country.”
