Those with CLASS never make a song and dance about it.
Once we had F tickets to DFW back when the A380 was operating. Remember there is a airbridge for F which they always seem to want to get F boarded and the airbridge stowed quickly.
So we were at the gate and boarding had already started and they announced "paging Mr and Mrs QS can you please come to the first class lane". Got a lot of "looks" as we were the only F pax to board
