Some of flights are marked for class of aircraft totaly unrealistic. For instance: the duration of certain flight is only 30-40 minutes, which is the clasification for class 1 aircraft, but in the timetable it is class 2, or even higher and this is far from reality.
The duration of the flight has little to do with
the class of the flight. Two relatively big cities
might be only 30-40 minutes away
but have a high demand of seats,
requiring a bigger plane.
I.e. in 2002 I was commuting weekly
from Munich to Dusseldorf on B737.
The flight would often be around only
45 minutes but the planes were always
quite full, no matter the many daily
flights.
So, it's not about the length of the
trip, is about the number of people
you have to move around, and EHM
timetable have been designed in this
direction, with bigger cities served by
bigger planes.
Ciao ciao!
