Iran plans to buy 114 aircraft from European plane maker Airbus (AIR.PA) as soon as March, and is looking for other deals, senior Iranian officials said on Sunday as their country emerges from sanctions and international isolation. The republic could need as many as 500 new planes over the next three years, lawmaker Mahdi Hashemi, the chairman of the parliament’s Development Commission, said at Tehran’s first major post-sanctions gathering of global businessmen.
