There used to be a link on www.jetblue.com to check which days a certain flight flies? I'm looking at B6-647 / 648 (BOS-SLC), and see that it seems to not be running in Nov/Dec/Jan, but then starts back up again in Feb. Seems odd since that is big chunk of ski season. I'm looking for something that will tell what days those flights are scheduled over the next six months or even more. I can't see to do that without lots of clicking on the reservation tool.

Basically, I'd love the best fare finder with a nonstop-only option.
