I’ve found some forum entries about this, but they date back to the beginning of the decade. I alerted Jetstar to this in March, and the problem has worsened since then.
Basically, I can’t book online, and I don’t know why. Consequently, I booked one flight with Air New Zealand and only managed, after huge effort, to get the other (for a colleague) with Jetstar.
Back in March, I couldn’t book with Vivaldi, but I was able to switch to Firefox. I let Jetstar know.
Now, this strategy does not work.
Before you suggest it, cookies and caches have been cleared.
Here’s what happens after I’ve selected the cities and the dates, and I go to select times. Let’s begin with Vivaldi on Windows, which is based on Chromium (which, as we know, is what Chrome, the browser Jetstar suggests you use, is based on):
Switching to Firefox now results in this:
Switching to Edge on the same PC gives this:
Fortunately, I also own Macs, so here’s what Firefox for Mac returns:
The only browser that works with the Jetstar website: Safari on Mac. As I’ve sold my Ubuntu laptop, I was unable to test using that OS.
Not many people would go to that effort, and while Jetstar’s Twitter staff (after some pushing from me in DMs) said they would refer it on, I don’t expect anything to happen.
Maybe Chrome would work, but I’m not ever going to download it to find out. Why invite Google on to your computer? But if that is the case, it seems foolish to limit yourself to such an invasive browser. My experience is that whatever is blocking me from booking with Jetstar (some may argue that this is a good thing), it is expanding across browsers.
