Figures on Travel Currency Outflow Unrealistically Small

A top official with Iran's Cultural Heritage, Handicrafts and Tourism Organization has called into question the recently released data pointing to the amount of hard currency that has flown out of the country through outbound travel, presenting differing figures based on ICHHTO's statistics. 
IRNA last week disclosed data—purportedly obtained from the Central Bank of Iran—that showed a total of $312 million in foreign currency at the official rate were allocated to people traveling abroad in the first three months of the Iranian year, which started on March 21.
This is while unofficial figures point to even larger sums. 
Meanwhile, Mohammad Moheb-Khodaei, travel deputy at ICHHTO, presented estimations that show a much larger number, ILNA reported.
