So now... back fresh and I've finally figured out connections, to where I had almost half a plane just for a one of my own connections at my hub. Majority of my routes come back to the hub in a wave and can connection to five different destinations.
(no idea how feeder works!?)
... but full plane still loses money.
So how do I fix my load problem? Also what makes a route inbound or outbound?
Only flights ever filling to 100% is MCO, PVD, MIA to the hub and leaving the hub. (long distance money makers)
with only 5 planes, waves that connect to 5 different destinations is excellent.
A flight is called a feeder flight if it brings a lot of transfer passengers to your hub. In smaller countries domestic flights often bring transfer passengers to the capital, from where they take an international flight. In the USA for example, a plane coming from the east could bring passengers who want to travel further to the west.
A full plane should not loose money. Possible reasons for loosing money are: the plane spends too much time on the ground (you also pay lease and salaries if the plane does not fly). The plane flies very short routes. Default price for a short flight is what... 77 dollar ? You still have to pay 11 dollar for passenger handling and 10 dollar for your on-board service. Or your prices are simply too low.
Flights that leave your hub are called outbound. Flights to your hub are inbound flights. Many airlines use odd flight numbers for outbound flights, and even numbers for the returning inbound flight.
If you juststart your airline, and you find a route that gets fully booked, forget connecting flights for the next two weeks. Launch several flights a day on that route. But with future waves in mind, you spread these flights evenly over the day. The flights that bring in cash, pay for your experimenting attempts to find other profitable routes. And routes that are not profitable today, may well be profitable next month if you offer more connecting flights.
So far your questions :-)
I don't know if I understood you well, but know that you can create and use several service levels. I suggest you create 3 service profiles: one for flights under 800 km, one for flights between 800 and 1500 km (with one extra meal), and one service profile for flights over 1500 km. Three or four green bars is the most you can get on short flights, but on longer flights I go for 5 bar service.
Don't be afraid of routes with competition. It could mean there is a lot of demand on that route. If necessary, interline with an airline on the other end. Interlining can be expensive, but if you have several flights per day to that destination, the IL should pay itself back. And communicate. It helps.
As Julian/Highscore said, don't forget business passengers. Like in real life, they are moneymakers for your airline.
Don't be afraid to use bigger seats. In theory, the game is perfectly balanced. If you use a seat that is twice as big, you can sell the ticket for twice as much. AS passengers don't care about the price. They only care about value for money.
Your ORS ratings should be good, especially on competitive routes. AS passengers are not loyal. Every day they look for the best way to travel from A to B. Increase your prices until your ORS rating is above 95. I always go for 99, but slightly below should not make too much difference.
Find someone on your server who knows the game. It is easier to give advice for a player who can check your ratings, or the check the fleet list, if he plays on the same server ;-)
