Greetings,
This is one of the most time consuming parts of AM, but it is part of the game!
If I were you, I would lower the fare by 1 or 2 Euros to regain 100% loadfactor. To be honest, having a load factor of 100% in your fleet becomes impossible and unnecessary the larger you get. When you first start out, it's very important as you need all the money you can get, but your airline (will hopefully) get to a point where you bring in so much money that it won't matter if your average loadfactor is 90%. Plus, you won't have the time to edit 200 + routes to get to 100% and even if you did, you'd have to go back and edit them again shortly after.
Simply put, no player has the time to edit all their routes to get a 100% loadfactor. You can try to edit the one's that are very small however (say less than 75%). Again, in the beginning, when you don't have as many planes or a high DOC, it's more important to edit it but as time goes on, it becomes less important (unless of course you are logged in and playing AM 24 hours a day non-stop!). The players here who do that scare me...
You can drop the fares by a significant amount, but that might affect your competition in a negative way. They might decide to *up the ante* by increasing frequencies or dropping it even further in retaliation. I consider it *the politest way of trying to share while getting 100%* if you lower it by just the amount necessary to get 100% (while you fight for the 100% you are still making the most possible).
It's unlikely you'll drive a competitor out of a market by lowering your fares by that much. Some players like me have no problems running a plane that pulls in a very small amount just to make a point. Some even run planes that lose money just out of spite. We are human after all!
Maybe the best advice is to try to stay *under* the pack for the longest time possible.
Let's say you have 8 competitors (I will make up somewhat fictional plane names)
a boeing 707 - $ 120
b caravelle - $ 185
c caravelle - $ 185
d caravelle - $ 185
e caravelle - $ 187
f caravelle - $ 190
g caravelle - $ 193 (you)
h skyvan - $ 642
i bushmaster - $ 665
You can edit the route to 190, 189.99 if you want, but sometimes it might be worth your while to edit it to 187, 186.99 or even 185 or 184.99. You will lose more potential profit (not all that much really) but you won't have to edit that route as much because you are *under the pack*. If you edit it to 190/189.99, you might get 100% loadfactor, but because you are in the higher tier it means you'll have to adjust it again very soon (the competition in the higher tiers adjusts their fares more regularly since they are the most affected).
Hope this helps...
