Safety comes first! This is a huge investment in time, energy, money, and most importantly your health. Don't be in a rush. The longer you stay close to your surgeon, the more followup you will have, and the more secure you will be that things are healing well. The longer you stay off your new fat cells in your new butt (at least a week), the better chance they will have of surviving. It is not a good idea to sit on a plane for long periods of time after surgery. It's very hard to know how much if any damage is done by traveling after surgery. How much fat can be injected depends on the size, shape and elasticity of your buttocks. Even more important than how much fat is transplanted, is how well the liposculpting is performed to harvest quality fat, leaving behind a nice figure. Best of luck.
