Tip:
At about 1745 gametime go to the Airport Manager's 
Office and bid for the Branch Offices available, 
Stay in the office until the end of the day.

When you return to your office the next day you will 
find that your bids for the Branch Offices were successful.

Continue doing this and eventually you will have all 
the Branch Offices available to you. 

This prevents your competitors from buying the rights 
and when you have all of the branch offices in your file you 
will never have to fly empty from an airport in order 
to collect passengers/cargo from another.
