Why are we even bothering to schedule 8 flights/week into Venezuela? Just do like Air Canada, stop all service. Countries like Venezuela who pull stunts like this should experience full transportation embargoes to be in place until the airline/whatever gets their money at an acceptable exchange rate. Venezuela declaring that the Bolivar is worth 32/$1 doesn't make it so. A lot of countries need to grow up and accept the fact that actions have consequences.
FYI, according to a currency converter I found through Google, the current exchange rate is 6.29 Bolivars to the dollar. So, Venezuela is attempting to pay out our money to us at approx. 1/5 of the actual exchange rate.
