State carrier Oman Air's losses narrowed last year and it required less financial support from the government as the airline boosted its capacity, chairman Darwish al-Balushi said on Sunday. Oman Air's losses narrowed 21 percent in 2015 to 86 million rials ($233 million), while its revenues expanded 14 percent to 466 million rials as it took delivery of nine new aircraft and increased its flight schedule. Oman Air has a fleet of 41 planes and plans to expand this to 70 by 2020, according to its website.
