It notes that the sanctions have left Iranian airlines with aging fleets in need of 400 new aircraft valued at $18 billion over the next decade. Rising fuel costs and high inflation are placing additional financial pressure on the airlines. However, domestic air travel in Iran is forecasted to experience strong growth of 4.8% annually through 2015 as the sector's share of business and leisure travel increases.
