American Airlines has joint ventures with several airlines, including British Airways, Qantas, and Japan Airlines. In theory these are “metal neutral” – it isn’t supposed to matter to the airlines which one flies a given route. They split the money.

In a recent employee meeting, a recording of which was reviewed by View From The Wing, American’s Vice President for Network and Schedule Planning Brian Znotins explained how they coordinate schedules with their joint venture partners, including who flies where and when.
