Mads,
I was in Economy too, 32H to be exact. Had a very sweet flight attendant bringing me an eyeshade and earplugs while apologizing for the galley noise. And I didn't even ask!
The flight was heavily overbooked in Y, but obviously chances for an upgrade are slim to none for us *Gs... A TG*G was sitting next to me and I saw the gate agent pulling pax randomly from the line and writing new seat numbers on their boarding passes.
Regards from SIN,
Lari
