I canīt understand why 7 airlines were founded at Beijing as this airport has only 10 slots per hour so far?
Maybe the same reason why you started there?
A good number of people, me included, simply are not interested if and who is at their airport, too. They do their thing and imagine to survive while others lose.
If you don't like the slot situation, I'm sure you can find some better airport in the world with less competition/more slots.
