Indeed, great for JFK! In doing further investigation, I noticed HNL-PDX/SFO, HNL-LAX red-eye and OGG-SFO have the seat map that reflects the reconfigured Extra Comfort, but not the lie flat F cabin. I'm guessing this is for flexibility in seating as those routes may not be lie flat committed just yet, but due to typical aircraft routing, there is a new config possibility. Other 330 routes have the older configuration.
Other interesting tid-bits I noticed... in mid January HNL-OAK goes to a 767, except Saturdays when it's a red-eye 330. However, there is some discrepancy between the seat maps and the flight schedule searches. The odd thing, is that I can't figure out where that 330 will be going. My guess is that the lie flat mod line picks up again, a plane goes to heavy check, the schedule shuffle is still in progress or they're waiting to change the online info to coincide with a press release.
