Oman Air, the country's national carrier, agreed in principle to rent six Boeing 787 aircraft for 12 years, Kuwaiti aircraft lessor Aviation Lease and Finance Co (Alafco) said on Sunday.

The first plane will be delivered in 2012, Alafco said in a statement, without giving a value for the agreement.

Alafco last month lost a USD$3 billion initial contract to sell state-owned Kuwait Airways 19 Airbus and Boeing passenger planes because the Kuwait government refused to approve the spending.
