In P3D and XP11 I create a flight plan with a third party program like for example Plan-G. Then I start P3D or XP11 and load that flight plan. Is this not possible in MSFS ? I see that Plan G gives the option to save a flight plan for MSFS but it saves it in P3D folder. But at any rate I don't see how I could have loaded it in MSFS

Copy your flight plan to

C:\Users\XXXXX\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState

than you can open it from MSFS directly.

This was a thread from last year :

But there are no menu option for loading a flight plan in MSFS

From the World Map screen press the <spacebar> or click "SPACE" at the bottom of the screen.

I use Simbrief, and their downloader loads it directly into MSFS. 

 

You can also open a flight plan from Navigraph in MS or even import a SimBrief plan into Navigraph, then open it in MS, etc.

In the bottom of the world map click 'More' and it'll take you to another sub menu. I can't believe they hid this further down for whatever stupid reason. Like others mentioned here, use Simbrief for creating the plan and Simbrief downloader to get that from their website into your computer and MSFS directory.
