We are booked with Jetstar next March (for Bali) and our flight schedule has changed yet again which is not a major problem.
However, you need to know that after all flight time changes ALL pre allocated seats drop out of the system and you need to ring Jetstar to book them again. (website has been down for a while)
I accidentally found this out a few days ago and noticed on our email the seat numbers were not listed as they had been before... on ringing I found there is already someone in one of our allocated seats bumping us to another row.
You need to act promptly if you get another flight time change.
