I use a 3 star scam IFS to make low demand regional routes profitable and base the airline in a smaller Middle Eastern city (As long as its not Dubai, too much competition) which will provide me with a central location for a hub and spoke stategy. Most African, European and Asian cities are within the range of DC-8s while 747SPs can reach Oceania and South America. I also try not to operate planes that are older than 10 years to keep the maintenance costs low and scrap unused airplanes rather than sell them to the used maket so they won't be used by other airlines.
