Branch office

Does openng a branch office increase costs? or am I thinking of interlining?

Surely there's increased staffing costs?

Thanks in advance.

Open a branch office does not require any cost. The cost will exist when you have flights to the airport or own a terminal building in the airport. So, the cost most probably refers to salary of staffs.

Ah, so staff salary is paid per flight, not at a set time every week?

No it is paid with the week-closure
