Big Iranian deal for Boeing

Iran’s flag carrier finalized a major deal with U.S. plane maker Boeing Co. to buy $16.6 billion worth of passenger planes Sunday in one of the most tangible benefits yet for the Islamic Republic from last year’s landmark nuclear agreement.

Iran Air’s deal for 80 jetliners is the biggest agreement Iran has struck with an American company since the 1979 revolution and U.S. Embassy takeover.

It has the potential to transform Iran’s creaking and accident-prone aviation industry, which has been hobbled by years of sanctions.

Those curbs have prevented the country from buying new planes from Chicago-based Boeing and European rival Airbus, and in many cases made it difficult for Iranian airlines to secure much-needed spare parts.
