Would I be a good candidate for AirSculpt BBL or is a traditional BBL a better option? (photos)

Based on your photos, if you are in good health, you appear to be a great candidate for lipo and a BBL.
With a BBL, the goal is to transfer fat from areas where you find it displeasing to areas in which you would like more volume. You have to consider not only which areas will have perhaps the best fat, but also you have to consider which donor sites will have the fewest problems afterward with the liposuction.  In general, the abdomen and thighs are preferred; but, if those sites are not available, fat from the sides, back, love handles, or other locations can be transferred to your buttocks and hips. If the waist was smaller at one time, the waist can likely be reduced to those same measurements or smaller provided the muscular and fascial integrity has remained the same.

Thanks for the question. 
In this regard, I recommend you waist and back Liposculpture, getting better curves especially in the waist, improving your body contour.
Finally, I suggested take the fat we get and transfer to the buttocks and hips, to mold them and get better volume, contour and butt projection, is that we know as "Brazilian Butt Lift" (BBL).Kind regards

Thanks for your question. You are a good candidate for a traditional brazilian butt lift procedure. When planning a Brazilian butt lift, patients can look forward to a double benefit: reducing areas of unwanted fat while gaining a perkier, rounded posterior.  Each procedure must be planned according to the individual needs of patients, harvesting fat from target areas of the torso, thighs or knees and transferring it to create smooth, attractive contours optimized for each person.That said, you definitely have to choose your surgeon correctly and make sure that he/she has the training and experience to meet your goals with absolute safety.  Best is a Board Certified Plastic Surgeon with specialized expertise in this procedure.
