How long does downtime usually take after nose filler before flying?

Hey everyone! I'm planning a K-beauty trip to Seoul soon and I'm thinking about getting some nose filler done while I'm there. The thing is, I need to fly back to the US after my trip and I'm wondering how much downtime I should realistically expect? Like, will I be super swollen and bruised for days, or is it usually pretty subtle? I've never had filler before so I'm honestly not sure what to prepare for. Has anyone here done it and then had to travel afterward? I'm trying to figure out how many days I should book between the appointment and my flight home. Any advice would be really helpful!
