worst
sorry worst would have to be Jetstar in Australia, they dont employ cleaners at all. the flight attendants pick up major rubbish but the aircraft mightn't be cleaned for about 8 flights until it gets a deep clean at night time. this is toilets as well people!!!!! the EBA for flight attendant doesnt cover cleaning and no allowance is given so the crew dont clean the cabin.
its awful as crew hopping on an aircraft and showing the passengers to their seats with chips crushed in the ground. but hey they are a low cost carrier and thats how management cut their costs i supose.
crew are great, very friendly but i wish we had clean aircraft.
