I had conversation with my friend, former AWAC guy, that you can't run empty E170s and expect to make money, he argued you can if you fill them with mail and aquire certain additional revenue streams you'd make money I said "what mail?", but then again I might have been inflating my own ego with "liquid courage" more than I thought. Though I think we both agreed that them pursuing code-shares was the only way they were going to stay alive.
