I am thinking of allowing the US to move bombers to India in a non-combat more in one turn, and then move the bombers to China on the next, either with a combat more or non-combat more. It took the US only two weeks to fly bombers from Seattle, Washington over the Atlantic Air Route, across Africa to Cairo and then to India. As for fighters, once landed at Takoradi in West Africa, they could be flown to India and China on the same air route. That was how the British were getting aircraft quickly to the Mid-East, and the route was functioning well by December of 1941. It took two weeks for a newly completed B-17E to fly from Seattle to Java in the Netherlands East Indies and participate in its first combat mission.
