Something to be aware of when booking with Jetstar

This is my personal experience with Jetstar, but it might apply to other low budget airlines as well.

During the checkout process, after you enter your PayPal or credit card details and enter "Submit", if you encounter a timeout error or any other error, DO NOT TRY AGAIN! Call the airline to confirm if the order has been placed or not, or you may be left with a duplicate booking.

Now if you end up with a duplicate booking, you can always call up the airline and get them to refund one of them. But the refund can take a looooonnnnng time. In my case, it took 1 month for them to approve the refund, and another week for the money to be refunded.

I guess I was lucky to get my money back. Some people weren't so lucky.

And did you know that 50% of Jetstar profit comes from people who buy a ticket and don't fly? I wonder what percentage of that is non-refunded duplicate booking?

Update: Line adapter for Ozito Blade Trimmer

Update (Dec 2021): If you access to a 3D printer, I would now recommend this solution , which makes it super easy to replace the trimmer line. I have been using it for a few months now with zero issue.

Line adapter for Ozito Blade Trimmer

This is an adapter for Ozito 18V battery trimmer (and possibly some Bosch trimmers as well) that uses a plastic blade for cutting. It lets you insert a 2.4mm trimmer line (about 8cm long) and use that for cutting. Simply cut a length of trimmer line and briefly heat up one end with a lighter so that a little bulb is formed. Then insert the trimmer line into the adapter and slot that into the trimmer as per normal. Make sure the trimmer line is not so long that it touches the safety guard. If that is the case, simply trim off any excess with a cutter or scissors. This part is best printed using PETG, which is a tougher and more flexible material. PLA is more rigid and breaks more easily. However, even with PETG, it will still break when it hits something really hard. Since this takes only 0.5m of material and 15 minutes to print, I will usually print a batch of nine at a time at very little cost. The blades that they sell do not break when it hits a hard object, but
