Jetstar: A few years ago, Melbourne to Tokyo, 8 hours late.
Recently Melbourne to Sydney, one hour late.
Sydney to Melbourne, two hours late.
Melbourne to Launceston, one hour late.
Launceston to Melbourne, two hours late.
Jetstar is nothing if not consistent. All flights come with screaming and badly behaving children. While crying babies must be tolerated by grumpy old men, not so badly behaving children.
We won't fly Jetstar again. I feel bad for the quite good staff who have to put up with such poor company management. It is not the fault of your check in staff or flight attendants, or even pilot. The fish rots from the head.
