My best experience was when I was OPUPed on S7 DME-LED flight. The agent on the bus was talking with someone on the PA and mentioned the load of 121 pax (S7 A319 had a J8/Y120 capacity at that time),but I could not beleive I would be the only one in J.

Business class bus in DME is normally the last bus to arrive,so they closed the doors as soon as our bus arrived...and yes,indeed it was only me....they gave me a personal safety briefing and closed the curtains after take off.

I did not get the J meal,(because S7 offers Y catering to the OPUPed pax,IF no one in the J cabin actually paid for the J tickets,which was obviously the case here),still it was a good and a relaxing way to get to LED and it was great to get 8 J seats for the price of 1xY.
