I've been watching Southwest's intra-California fares for mid-June through late August. They are still stratospheric: $113 to $123 even for the most off-peak flights. Clearly these fares are a placeholder until Southwest decides what the market will bear this summer. The market will not fill short off-peak flights at minimum fares over $100.
You're under the assumption (not assuming as I originally typed) that this isn't what the market would bear. It sounds like it's not what NSX would pay. If the other travelers are, that's what the market is.
What you're *not* saying is that any other airline is cheaper. With planes pretty much filled, there's little incentive for anyone to drop their prices.
