A 1.5 hour flight 3 days after breast augmentation may be reasonable for some patients, but it should be cleared by your own surgeon because it depends on how the surgery goes, your health history, bleeding risk, pain control, nausea, and whether there are any early concerns at your postoperative visit. The main issues are comfort, access to your surgeon if a problem develops, and reducing blood clot risk. Before flying, you should be walking, eating and drinking, able to manage pain without excessive sedation, and have no concerning swelling, bleeding, fever, shortness of breath, chest pain, or calf pain. Try not to travel alone, do not lift heavy luggage, stay hydrated, and walk during the airport/flight when safe. Your surgeon may recommend compression stockings depending on your risk factors. Many surgeons prefer patients to stay locally until the first postoperative check, and some prefer longer. Ask your surgeon exactly when they want to see you before you leave and what you should do if a problem develops after you return home. If you develop chest pain, shortness of breath, fainting, one-sided leg swelling, severe breast swelling, or active bleeding, seek urgent medical care immediately.
