SOP ?
I remember joining Lauda Air in Vienna some years ago now , and the thing that struck me was the incredible cleanliness of the aircraft , inside , outside , front , back , galleys , wheelwells ...............
The Flight decks were like the aircraft had just left Seattle , with loads of paint brushes and wipes available at all times.
The SOP was that any crew boarding an aircraft who found things not as they shoud be ,reported it straight away ie , before they got blamed for it !!
The inbound cabin crew were responsible for leaving the cabin in immaculate ready-to-go condition before going off duty( with the aid of kosher cleaners etc ). This virtually ensured the on-time departure of the next flight .
It was hard to work out the age of the aircraft while sitting on the Flight Deck , like flying a brand new aircraft every day.Every scratch on the panel was touched up etc , otherwise the main man wanted to know why. The aircraft were like his personal fleet of Ferraris and Mercs - you do not leave them disgusting , so why would you do it to a $50 million aircraft ?
Is it so hard to do ?
My next airline was a Big Airline in UK and the difference / filth was shocking.
