Flying to Hawaii in March with Jetstar. Booked during a sale in May. Checked my flight last night and they have put my return flight home forward by 4 days( no notification). I am not at all upset as i am happy to spend the extra time in Hawaii but it means i have to change my hotel dates and maybe get an extra couple of days leave from work. My question is, are they likely to change again, should i change my hotel booking to match now or wait a bit.
