VA 777-300 boarding at row 1 door or row 5 door

I would imagine that may vary by airport re the Aerobridge and NIGS setup.

 

I can only comment on the flights I've taken to/from LAX but at all airports on those flights (BNE, SYD, MEL and LAX), we boarded and deplaned through the Row 5 door.

 

Have not used them at LAX where all the gate shots show the first door not in use. My only expereince was at KUL where both were used:

Last 3 flights out of TBIT the door near row 5 was used

Last flight from Sydney at Easter , they used 2 doors for boarding row 1 and 5 with J pax using row 1(first time i have seen this) . All other times it was one door at row 1
