What is the shortest passenger route served by wide-body aircraft (i.e. B747, B777, A330, A340, A380 etc.), preferably on daily basis, preferably by Lufthansa (but any airline flying from Frankfurt will work for me).
The shortest one, I found, is FRA-IKA (Frankfurt-Teheran) direct flight with less than 5 hours of flying, served by Lufthansa on daily basis with B747.
To my knowledge the shortest wide body scheduled passenger service from Frankfurt is the British Airways flight BA0903 to London Heathrow which is operated by a Boeing 767.
For a short time after the introduction of the A380 at BA, this route was served by an A380 to allow more crews to familiarize themselves with the aircraft in a short time.
LAN flies FRA-MAD route on a 787 with prices as low as 200-300 euro return in business.
In general, you could search with matrix using a one-way search such as:
Departing from: FRA::N / aircraft t:300 t:310 t:330 t:340 t:350 t:380 t:747 t:767 t:777 t:787
Destination: LON,PAR,GVA,MAD
Adjust according to desired aircraft and destination.
I could find this flight Kuwait Airways flight 175, an A330-200 flying from Geneva to Frankfurt on a 3 per week basis..
