Apologies for a newbie question - I'm pretty much a B6 newbie.

A year or so ago they initiated three-class LAX-JFK service, with lie-flat beds in biz and first. Seemed awesome.

Today I'm having trouble understanding what that product has become. ITA shows A320 on the route, and offers I and D fares (biz). SeatGuru doesn't have seat maps for the flights I looked at. And I couldn't find anything specific about a/c configuration or seating on the JetBlue web site. Help?
