You said LHR
are not the same route - I said that wasn't neccesarily the case, it's possible to follow the same route on the return leg.
Next you say that you aren't talking about the route in terms of coordiantes/waypoints, but in terms that for a passenger route.
The difference is a passenger could book 5 LHR
tickets and as far as they are concerned they have travelled the same route 5 times, but the aircraft could fly a different route each trip they took - 5 different routes. Passenger routes do not specify airways, waypoints and coordinates.
It's a simple concept that the outbound and inbound legs of a flight can follow the same route - if you drew it out on an airways chart there would only be 1 pencil line on the map because both legs of your flight followed the same physical route.
If you're still stuck, ask a grown up.
The meaning you personally want to inist on for the term route is up to you. The fact is in reply 2 you missed the whole point of the thread - it was about the difference between outbound/inbound flying times between a given city pair. The examples quoted were;
San Fransisco-Manila 12h30
Manila-San Fransisco 12h30
Lajes-McGuire AFB 7h30
McGuire AFB-Lajes 4h10
Talking about different flying times between La Guardia and Orlando dependent on aircraft type is not the point of the thread.
Hats off to you. I think it's amazing that even with 150+ posts per week, you can still manage maintain the same quality in every single post... There are few here on airliners.net that are so consistent.
