You are in luck!
The best way to fly a path repeatedly is to save the Mission Plan so it is on your device. This saves it locally and also to your Maps Made Easy account. When you sync your other devices in your account it will pull the Mission Plans that have been saved on other devices attached to the same account.
That is all great for devices on the same account, but you can also share a Mission Plan as a .MME file by swiping left on a saved Mission Plan and selecting the "Share" option. From there you can send it to whoever needs it.
