Last time in Doha 2011 - I dont recall this mess.
I realise that handling baggage and frieght can cause some litter - tags dropping off and packaging becoming ragged and blowing in the wind.

Yesterday arvo, taxying for takeoff at Doha airport, I was disgusted with the view out of the airplane window, litter and rubbish everywhere. I thought I was on the access road to the local rubbish tip, rather than sitting in 1st of a A321.
Seems so easy and low cost to fix !
