First off, apologies for opening up a 6 year old thread. Rock and hard place; either do that or start a new thread and be policed anyway

Anyway....I am on my first BA A380 journey, to IAD. Previous A380 experience is with QR. We boarded through C63, and as far as I could see, there were just two airbridges and both went to the lower desk. I admit that I didn't really get a good view from the gate.

As I am in 2A, and the first airbridge is rows 1-4 only, so I couldn't see which pax went down the other route(s).

Is it likely that they boarded using just the two? Or have I simply missed seeing a glaringly obvious airbridge?
