I would drive.

I live about 6 hours from the hospital in Kelowna. Two days post-op I was released from the hospital. We had intended to stay one night in Kelowna before starting the drive home but I said to my wife who was driving, "lets just do it now." and off we went. We drove 4 hours, stayed in a hotel, and did the last 3 hours the next day. We stopped about every hour for me to stand and readjust. Take lots of pillows.

Your choice is a 4 hour drive or a 1 hour flight. I fly quite a bit for work and a 1 hour flight is almost a 4 hour event anyways; getting to airport, checkin, security, gates, flight, drive home. The biggest difference is that the airport and plane is a very public place. Given your condition it will be much more comfortable being in a private place such as your car. Uugh, couldn't imagine flying after getting out of the hospital.

Trust me, you'll do fine in the car.
