What I want to know is why do people grab FRA - SFO flights faster than the LHR - SFO flights (UA, not LH) - as in - are those planes from FRA with better/newer F/J seats?
Obviously, if you are flying from FRA itself, then it makes sense; but there are people connecting from other parts of Europe (like ZRH) that have the option to connect in FRA or LHR and it seems that the FRA flights go first.
