If you’ve been cleared to a waypoint off your route and haven’t been cleared past it, a couple of minutes before the waypoint “request clearance after XYZ”.
That’s what I do, of course, but unless ATC has forgotten about me, they must have some expectation of what I’m going to do. Or they have, in fact, always forgotten about me when this happens..
The USA are one country, you can’t compare that to Europe. Compare flying from Germany to France to flying from the USA to Mexico. Let’s see who is first to finish planning and taking off…
It is the same process as far as getting a clearance and dependent on the country of origin. As long as the flight starts in the US, the filing of the flightplan and obtaining the clearance is the same. Now, if you start in another country and end in the US, it is a different story.
