Jetstar's International schedules only go up to Jan 31 2009. Pretty sure that JQ will do some big changes to their International schedules like:
-Decrease Japan Services
-Decrease HNL services
-Increase Kuala Lumpur
-Increase to the land of Thai
-Increase Bali

I doubt any new routes or deleted routes, but Japan services will most likely be reduced from hearing about VERY low loads, and merging flights etc

Anyway, just my two cents, care to comment
