Over the last 15+ years we have been regular Jetstar travelers and very happy your service till now. Jetstar's lack of refunds is rubbish. Credits don't work for us as we have very specific travel periods which are not changeable. For us to fly with you again, Jetstar (and all airlines) are going to have to provide refunds to flight cancellations, period, no exception. If the flight is cancelled then automatic refund, no time delays. Airlines that adopt this sort of policy will thrive and the rest will struggle. Refund policy will guide our travel selections in the future.
This is just our thoughts on where airline companies needs to head.
