Missing maintenance
Just had a flight on China Eastern flight on an A300 or A310 from PEK to Shanghai and being a professional I was surprised about the not working lightbulbs in the cabin. 75% of all NO SMOKING signs and FASTEN SEAT BELTS signs did not work. This is a clear sign for me about attitude towards safety and maintenance. Those lightbulbs just do not die on the same day and to get to a state where 75% are not working, it takes a very long time.
But I was impressed by the friendly service and the good service on the short trip, even in economy class.
