I'm still surprised they dropped LAX-LAS. It's a leisure market, sure, but there's still a lot of traffic. Maybe the aircraft management didn't work if LAS wasn't a hub.

BOS-LAS was one of the last non-hub flights to LAS. I was just in LAS this morning (for LAS-PHX); half of the A concourse is fenced off.

BOS itself seems to be a mini-focus city, between the shuttle and the other direct flights.

Generally the 9xxx flights are ferry or other irregular flights.
