Interesting quote from that article:

“[W]e are targeting the under-served in the premium market. This includes small business owners and those paying for travel themselves.”

This makes sense. On these routes, there really isn't anything between Y+ (say, $250/ow) and J (say, $1000+/ow). I'm interested to see what the B6 premium seats price out at.

Decent pricing and B6 joining Pre-√ will sway a good chunk of my domestic travel, I think.
