I am about half way through my instrument rating but I travel cross country regularly, typically 3-400nm. I use flight following religiously for anything other than pattern work. While I plan my flights and brief in detail, I typically don't file a VFR flight plan. Note: I use fore flight for planning and briefing. My questions: 1) If I do file a plan, when I request flight following, will the controller see it and will that help them to know my intentions (other than destination which is always provided)? 2) If I am using flight following and giving the controller my route, is there any benefit to filing the VFR flight plan? 3) Since ForeFlight has all my flight data for giving me the briefing, does this get noted by FAA as me requesting information for my particular flight.
