I recently arrived at Z (unclean, i.e. the arrival corridor leading to transfer security). There were two sets of signs, one pointing towards the higher A gates (50 - 69 I think) and then one for lower A and B, C, D, E, Z. I followed the latter but I was wondering if I could have made a shortcut following the former - I was heading for the A SEN lounge, and basically everyone went for the second option making the lines long. What would have expected me following the A50-69 signs, where would I have ended up?
