Hello, I'm new here and this is my first full game. My load factor has been decreasing in the past several (real) days. Most of my routes now have LF below 55 and this is not a problem to specific routing or timing. I have tried to decrease the prices but it seems price management only affects short run. What are meaningful ways to increase the LF? Another question is, what LF should I maintain to make profit? I have already seen loss weeks with LF = 55%.
It is impossible to name an LF you should aim for. Obviously higher is better (up to a certain point), but some players are profitable with 40% when others need 70%+. It always depends on your environment, you can't generalize this.
Your LF will have suffered because the competition buffed up capacity on the routes. That's a perfectly normal thing especially early in the game. You should not overestimate the influence of pricing. It is usually not a smart thing to reduce prices at all, and even less so if you are the weaker competitor.
The only way to sustain a good load factor in the long run will be to spread yourself thin, so don't serve the full demand on routes, fly few flights on trunk routes, etc.
The moment you or the competition begin competing for market share, your LF will plummet. So if you are not confident you would win an all-or-nothing battle with a competitior, you should rather remain small to medium sized and aim for maximum profitability - a good LF will happen on its own that way, as it's only a display metric and not of any direct relevance for the profitability of your company.
