I depends on how fast you heal.
If like me you heal fast then you'll be fine to sit on a plane for a couple of hours after a month or so...
You do get rather tired in the first couple of weeks. But after that it was ok as long as no one expected me to concentrate on anything too demanding - the biggest problem, which was why it took me a full two and a half months to gte back to work, was that my head was all over the place and it took all of that time to put my brain back together! The Euphoria you feel just seems to scramble everything.
It was the same with the revision op - that was in Jan - I'm only just starting to get mentally fully back in harness now!
