How long do I need to wait before flying after abdominal surgery?

Hello! I'm planning to be in Seoul at the end of this month. I've been very concerned about my stomach shape, so I decided to get fillers while I'm here. However, I have to fly to Australia 5-6 days after the procedure...

If anyone has had this done, what is the typical downtime? I've heard there are daily effects, but how many days does it actually take for the active results to show, and how long until the final results are visible? Should I expect swelling before flying? If you have any distracting materials or tricks, please share!

I wish you all the best and hope to meet those who are interested in requests and ideas 😊
