Virgin America A320 N629VA on the gate preparing to depart as VX415 to LAX. Last flight on the long trip to LAX via Abu Dhabi. Foggy at JFK. Long taxi with about 12 planes in line to depart before us. About 45min from pushback to takeoff. We've got some minor turbulence predicted for the first hour or so and then should be smooth the rest of the way. Thinking I'll sleep most of the way. Been a long trip and a big day on our NYC transit!
