My last OZ flight (ICN to LAX on A380 in business class) featured the previous passenger's used toothbrush, snack wrappers, and scraps of their food sitting next to the window when I boarded. Everything was also suspiciously sticky. Flight attendant was in shock and we had to clean it together while taxiing to the runway. Incredibly disgusting experience.
I always found OZ to be one of the cleaner airlines (especially compared to American carriers) but this was the first time a used toothbrush was waiting for me at my seat! One-off or a trend of cutting back on cabin cleaning time?
