cmon0005, many thanks. As with all airlines, the list of delays shown is not exhaustive. None of us can cover every delay and sometimes diversions occur of say a flight approaching DXB or enroute across the Pacific at a time in east coast Australia when most AFFers are sleeping, so any contributions from others are welcome.
It is especially good when 'on the spot' AFF members report on what is occurring at the coalface. Some have been paticularly helpful in informing us as to how they were accommodated overnight in an hotel or rebooked by airlines. This is good bargaining information for members, particularly in respect of low cost airlines whose record in handling long delays from a passenger perspective can be less than stellar. Generally, legacy airlines such as QF, SQ, CX, JL, NZ and numerous others are better at this. perhaps explained by the higher fare structures.
Because of our geography, QF in particular has a number of very long flight sectors, so quite often if one flight is delayed departing from say SYD or MEL, a passenger booked on the return flight can 'know' 15 hours in advance that his flight returning will be late leaving. On occasion this can be in advance of any notification from the airline. Sometimes AFF members such as Flyerqf and myself can more or less predict that say QF28 will form QF25, so if QF28 is badly late, passengers booked on QF25 may be required to overnight in SYD as has recently occurred twice.
Delays are incurred by all airlines but the more significant ones can be of interest as they may show a pattern, and then influence along with many other factors the choice of airline. Safety is far and away the number one consideration but it is a bit of a 'given' although we are all grateful to pilots and their associates on all airlines who maintain a takeoff to landing ratio of 1:1.
