Do you know there is a division of labor in the airlines industrial? I think it is more than 30mins as a lot of time we have to wait for the AC outside and wait for the cleaners to do their job. The catering replenish for all galley food and beverages, cleanersto clean the aircraft to clean the carpet and floor and some will change blankets and pillow cases and all blankets and pillows are seal with plastic bags. Yes, I agreed the AC is not clean but I do not know why a lot of customers will walk on the AC on bare feet and never flush the toilet after using??
