That's what I was getting at. But is this just a commodity, really? What are you doing that is unique apart from owning that many engines?

Owning that many engines and having the maintenance support. Yes, having our own QuickTurn shop, which does module swaps, and having the maintenance at Lockheed. Our maintenance cost is not $7 million like everyone else when going to Lufthansa or MTU. That's a benefit too. It's the whole picture. Being able to supply our own parts is significant. We can essentially do everything that people would need multiple vendors to do. Anytime you can have it in-house, there are big benefits. You have to make it work, but we do it. That's the benefit.
