My partner suffered from a punctured lung on last week from a small knife wound he is now home and recovering but how long after would it be safe for him to fly

You will have to discuss that with his doctor. It would be unwise and dangerous for you to get that kind of information from strangers over the internet who don't know his medical history.

Could you maybe give me a estimate as he isn't at the doctors until Tuesday and we have a holiday booked for 19th July do you think it would be OK by then

I can't give you an estimate as I don't know his health history. Tuesday is only 2 short days away. He has plenty of time to talk to his doctor.
