Not sure the amount of development work involved, but seems like Jetblue is throwing money away by not pricing J class flights where the shorter leg is in Y.
Just trying some combo's now on google flights. PIT to SAN

a couple of flights show up when looking from J pricing, but it doesn't let you book that on JetBlue website.
same with PIT to LAX and PIT to SFO.

PHL/DCA to SFO/LAX looks to have pricing on Jetblue website, but it's actually so much more than buying legs individually.
If they plan to fly to Europe at some point, they really should get this ready for mixed class pricing ready for combos like DTW/DCA/ORD/PIT to London via BOS.
