Yes it will contribute a bit, though less stops and better connection rating on each flight will contribute more (the connection rating is next to the flight, not the one under the flights). Remember that if the passengers have to wait more than 3 hours from that the plane they come in land and the departing plane takes off it will impact the total rating.
How about being shortest journey time? Does it contribute too?
Is there well described post or wiki page to read on "Connection Rating"?
At least at my business' hub I am trying to keep minimum transfer time which is 60 minutes, but I read somewhere that It is good to add just a single minute so I keep connections at the hub close to 61 minutes. Until slot runs out. :lol:
Yes, the shortest total time the better your rating will be and the more passengers you are likely to get.
The reason you should add an extra minute is that the system works in seconds but displays only minutes, so values are rounded. So a flight that shows as arriving at 13:00 may actually be arriving at 13:00:20, so if you have the next flight leaving at 14:00, the connection time won’t be 60 minutes but 59 minutes and 40 seconds, not enough to make the connection.
