My surgeon wouldn't let me travel by plane until one week post op. I live in Chicago and had my surgery in NC. I travelled about 2.5 hours away in a car to a friend's house by car to recover for the week. Everything was fine in the car and later on the plane. Just make sure that your seat belts don't touch any of your incisions.
I only have one near my belly button. My surgeon, Dr. Paul Enochs, specializes in single incision surgeries. I am five weeks out & had zero complications.
