Hello phyre, It’s a pleasure to answer your questions! Plastic surgeons have different post-operative protocols, customized for every patient to achieve the best results. I typically suggest my patients to avoid traveling at least the first 8 weeks after Brazilian Butt Lift (BBL) surgery. Putting pressure on your buttocks by sitting down or laying on it, especially for long periods of time, can stiffen, deform and even cause the transplanted fat cells to reabsorb. In the case you can’t absolutely elude getting in a plane, I recommend you sitting in a modified position, placing a bolster or rolled-up towel under the back of the thighs while sitting down, as to avoid significant pressure. Also, there is a variety of post BBL surgery support cushions available on the market. Moreover, your surgeon may prescribe you an anti-coagulant medication to prevent a deep venous thrombosis when you travel, especially for long flights. Good luck and may God bless you! Dr. De La Cruz.
