on the new config with the signature interior, the crew seats on the upper deck are located in front on 10JK only. Nothing in front of 10AB. However, not a whole lot of difference because there's a lot of leg room for the exit row seats. You'll only notice the difference during takeoff and landing.

personally i still prefer J/K because leaving LAX, i can see the CA coastline...and sometimes the flight path takes you over vancouver so it's nice...
