How soon after BBL can I travel? What about attending a concert/music festival?

Recovery
timelines vary from person to person, with general guidelines recommending that
patients avoid putting pressure or sitting on the buttocks for two weeks. By
three weeks, a short, two-hour flight should be doable, so long as you get up
and move around every thirty minutes. Only your surgeon can correctly assess
what post-op activities are realistic for you, though most people should be
able to attend a concert three weeks after a butt lift as long as they avoid
physically strenuous exercise (such as vigorous dancing.) It’s best if you
clear these travel plans with your surgeon.

At three weeks out, you may be OK to travel,. This is something to review with you surgeon. This will depend upon how well you have healed.
