In my opinion, the important part of the upkeep of ALL aircraft is to keep it flying safely. If the turnround is tight and the cleaning isnt up to scratch...so be it. If its safe and airworthy...who cares about a bit of mess now and again.
The A330 will not operate shorthaul this September from Manchester.
And there were no A330's in LPA yesterday....A320,A321, B752 only
