He's not talking about that. When he says that the WN model gives up more revenue, he's probably referring to their point to point system. The hub and spoke system allows you numerous city pair options between a given O & D. That accounts for a lot of revenue contributing to your network. By only serving point to point, all that connecting revenue is lost because you're only offering a flight between Point A and Point B, or Point A and Point D, with stops in Point B and C along the way. I think that's what Dave is referring to. Everyone likes to talk about how the hub and spoke system doesn't work anymore and that it's broken. Not so. While it needs to become more efficient, the fact of the matter is that giving up the hub and spoke system would give up far more revenue than you'd save in costs.
