How long until I can fly after getting nose filler? Worried about the flight home

Hi everyone! So I'm planning to get nose filler done while I'm here in Korea, but I'm a bit nervous about timing since my flight home is in about a week. Has anyone done this before and can tell me what the downtime is actually like?

I know it's non-surgical so it should be way less intense than surgery, but I'm worried about swelling, bruising, whether I'll look totally obvious on the plane, haha. Does anyone know roughly how many days before you can look normal-ish again? Like, is it a few days of looking puffy, or more like a week?

Also, if anyone's flown right after getting it done, did the plane pressure or anything feel weird? I'm sure tons of people do this and it's fine, but I'd feel so much better hearing from someone who's actually been through it. TIA!
