Are there any specific things I am able to do regarding international flight after BBL/BA?

Every surgeon will have a different postoperative routine based upon your health, the procedures performed, how you are recovering, and travel destination along with mode of transportation. Sit with your pillow on the flight and in the car and have your plastic surgeon sign a letter to the flight attendants requesting that they let you walk the aisles every 30 minutes. I would rethink the decision to fly to a third world country so soon after surgery.

Dear anamkidwai,
every plastic surgeon has his own postoperative protocol which he recommends to his patients. I would suggest you to discuss this with your plastic surgeon.

Hello dear!!
Thanks for the question and provided information as well.
I recommend my patients to wait at least 10 days before flying back home, and you should not sit for more than 30 mins. every two hours, for the first 2 weeks, and always with the help of a boppy pillow. If you have any concerns, I suggest you follow up close with your plastic surgeon.
Hope this is helpful. Good luck :)
