Although DOT wasn’t ready a year ago to approve an expanded joint venture between American and Qantas and it was possible they might ask for certain concessions in exchange for doing so (they’re asking for slots from Delta and Aeromexico at New York JFK and Mexico City in exchange for approving theirs) history suggested that American and Qantas would be able to move forward.
However — although Australia and New Zealand authorities already signed off a year ago and although DOT allowed a joint venture between US carrier Delta and Australia’s Virgin Australia — the US Department of Transportation is blocking the expanded cooperation between American and Qantas
