I have booked two flights next year in January and February (Australia and South America), which consists of 8 segments each and four different carriers.

Now I receive every week an email, that there is a change.

Following changes I received:

- Departure time changed to 5 minutes earlier
- Arrival time changed to 35 minutes later.
- A changed flight, on which the departure time was changed to 5 minutes earlier, will now depart 10 minutes later
- ........

I thought the flight details are already in the system, because they are all bookable. But why do the carrier (LH, SQ, NZ, TP, LX, OS) change the details now every week ?
