For a revision, I'd leave more buffer than the clinic suggests. Your situation is different from a first-time case: scar tissue and the existing damage mean swelling can linger and the final shape takes longer to judge, so a short trip can leave you guessing. Ask the doctor how many follow-up visits they want and whether they'd clear you to fly based on a specific check rather than a fixed date. Build a few extra days after the last appointment, not just before surgery.
