When can I fly home after surgery?
Rule of thumb (your surgeon's letter overrides): 2-7 days after uncomplicated laparoscopic surgery. 2-3 weeks after most open abdominal surgery. 4-6 weeks after CABG or orthopedic major (hip/knee/spine). 2-4 weeks after dental surgery. Longer for ICU stays or complications. Watch for DVT risk on long flights post-surgery — compression stockings, hydration, and occasional aspirin (confirm with surgeon) reduce risk. Fit-to-fly letter from your treating doctor is required by most airlines.
This answer is general information, not medical advice. Your own doctor should confirm what applies to your case.
