I looked at the link to the LX forum, but I am still a bit confused about what I will need to do during my 1 hour at GVA (assuming first flight is on time). I had planned to check my bag all the way through from Barcelona to IAD since it's on one ticket, and thus not deal with my bag at GVA. I now understand that I will need to go through passport control at GVA to switch to my US departure gate, but will I need to retrieve my checked bag and re-check it or can I just forget about the bag? Thanks.
