I took this route in 2010 after the fantastic Guca festival, so I also thought it could be Jooned
I was in C which was only one row, the flight was overbooked and I volunteered at check-in, got 150 EUR or so, then eventually they had space for me, got premium economy (2nd row) with an empty middle seat, therefore business service with the terrible white boxes. And I got to keep the volunteering voucher. The game was much more fun back then
