How soon could someone do a 15 hour flight?

Any input appreciated.

I assume you want to fly after having surgery. I was not earied to fly until a full seven days after surgery. Took a flight on that eighth day with two legs for about 8 hours. Now, was I smart to do this? Hmmm. Question is how well you will be able to hydrate during that time frame. In 15 hours is it good to go without protien and just Water? Since you can not take in liquid protien through security yiou are going to need to consider this. Hydration is key after sugery.

So - yes, you can probably do this, but consider what you are going to do if you have any complications? You are up in the air without medical attention. If you have a leak, you could be a a heap of trouble. Consider legging your trip into smaller portions, where you can get a hotel room ,rest and drnk some liquid Protein. I was exhaused after return trip and slept for the next week to recover from lack of hydration and protein.

Ask your surgeon. If on day of flight, you are not feeling right (would say gut feeling here) rebook. Good luck!
