How long after having a TT can I go on Vacation?

Your plan seems very reasonable. Some general thoughts: The recovery experience will vary from one patient to another but, generally speaking, the recovery experience associated with tummy tuck or mommy makeover surgery is often underestimated by patients. In other words, it is a significant operation associated with a significant recovery, both from the physical (and often) emotional standpoints.
Fluctuating levels of discomfort is quite common and may be related to several factors. I think you have a good understanding: increased discomfort may be related to overdoing activity or may be related to being stationary for too long.  Other factors that may be involved include  inadequate pain control medication levels.
 Ultimately, it will be important that you "listen to your body" and titrate your activity level as well as pain control efforts carefully.   You will need to achieve a balance between gradually increasing activity (I tell my patients it is similar to a "rehabilitation" after any type of trauma) versus overdoing activity and experiencing a setback of some kind.
 Your plastic surgeon should be your best resource when it comes to helping you titrate activity level; in my practice, at this point in your recovery, I would likely suggest that you try to get outdoors (with assistance), even for short periods of time. My patients find a use of a walker very helpful during these early postoperative days.
 It is not unusual for some patients to require several months before they regain preoperative strength/stamina/energy levels.   What I have observed  is that many patients are about 70 to 80% of their energy level at the 4 to 6 weeks post op period and may require 3 to 4 months before they are 100%.   Again, it is not unusual for patients to experience significant emotional "ups and downs" as well.
Best wishes for outcome that you will be very pleased with.

Thanks for the question. Generally, most patients can fly within 2 to 4 weeks after Tummy Tuck surgery. However, car or airplane travel should be avoided to prevent the risk of blood clots in the legs. I wish you all the best.

Thank you for your question.  A tummy tuck (or abdominoplasty) is a major surgical procedure and your body needs adequate time to heal afterward to achieve an optimal result. I advise my patients that they should expect to be off work for 3 - 4 weeks depending on their job. Recovery is usually 6 weeks and then patients can return to all activities, but it may take up to three months to feel that you have completely recovered. That being said, I think a November surgery would give you plenty of time to heal before your holiday. Your best option is to choose a specialist plastic surgeon (if you haven’t already) and follow their postoperative advice, as they will be familiar with your specific procedure and case. Good luck!
