777HD DEN-LAX today.

I arrived at the tail end of BG1. BG1 and BG2 were not boarded together. F (and preboards at anytime?) had access to L1. BG1 and I assume all remaining groups used L2. FA's were directing people onboard.

We departed ~30 minutes late due to late arriving fuel. It was for the best as we were able to accommodate a few folks that would have misconnected, and we still arrived on time.
