You clearly weren't at LHR during the pre-Christmas snowgate saga then. The Flagship check-in was closed and the main F/J check-ins were around thirty or forty people deep at one point. This was after you'd got past the door-trolls who were only letting in people with a confirmed seat on a confirmed operating flight leaving within three hours.
