My plan is to fly a random route on the most favorable route for winds during a changeover or during opposite direction flow.
So if all East traffic is at 54 and below, I'll be westbound up at 58 all by myself, so it should be easy to get any route and altitude for direction of flight.
Does this sound like a good plan?
Shortest route, good winds, best altitude, sacrificing departure time.
The answer is that any time that the OTS is either not operating - in the 4hr break could be used. As you say going Westbound overnight or Eastbound during the day also could work but the OTS follows or avoids the jetstream and there are times when the eastbound tracks are are surprisingly far North, and the westbounds well south.
Go to [URL="https://earth.nullschool.net/#current/wind/isobaric/250hPa/orthographic=-35.79,31.29,610"] and have a look at the 250hPa level
But the avoidance of CPDLC and ADS-C will not last long by 2025 the North Atlantic will no longer have a track structure and all routes will be diverse 'user preferred' or 'business' trajectories.
