Yeah unfortunately in SKG, I got to the airport to be put on the next flight which happened to be boarding imminently so didn't have a chance to go to the lounge.
The agent first asked me to put my luggage in the carry-on sizer until she looked at my ticket and saw I had a business class seat and just let me through.
Think everyone else behind me got their bag checked though during boarding - so for my data points/stats I counted that as one where they checked the carry-on luggage.
