As war in Iraq gathers pace insurers will begin charging extra for war insurance on commercial flights into the Middle East, according to Aon.
Aon said Kuwait was among the countries where higher rates were being imposed.
Additional costs would be highest for countries bordering Iraq, including Kuwait, Saudi Arabia, Jordan, Syria, Turkey and Iran.
Aon Aviation specialist Robert Karl said there was no consensus on which countries the insurers would require surcharges and how much charges would be.
He said: "That will be sorted out over the next few days. There are going to be certain areas where they won't provide coverage, certainly within the war zone. And I would assume Kuwait would be one of the hotter spots."
Contracts for war insurance usually provide for cancellation seven days after a war begins. Karl added however that once the war begins insurers are free to raise their prices.
