Thanks, another thing missing. I'll have to look through the old books to decide what the cost will be.
This is what I think I'll use.

STARSHIP EXPENSES
There are five basic expenses (in addition to the bank payment, if necessary) associated with starship operation:
1. Fuel. See Fuel Benchmarks pg 360 T5.
2. Life Support. Each occupied stateroom on a starship involves an overhead cost of Cr2000 per trip (two weeks) made. Each occupied low passage berth involves an overhead cost of Cr100 per usage. There is a normal limit of one person per stateroom, travelling couples or groups usually taking adjoining staterooms. Military vessels or chartered ships may be used with a double occupancy system (two persons per stateroom), but this requires twice the normal cost.
3. Routine Maintenance. Annually, a starship should be given a complete overhaul in order to insure that it is kept in good working order. Such maintenance costs 0.1% (1/1000th) of the cash price of the ship, and requires two weeks at a class A or B starport. The owner must make provision for payment of the maintenance fee when it comes due. Crew members generally take their vacations at this time, but must still be paid. The ship owners must make provision for the expected loss of revenue while the ship is out of service.
4. Crew Salaries. See Costs pg 52 T5.
5. Berthing Costs. Landing fees, handling costs, facilities use charges, and other starport fees are a common practice, and such costs must be paid as they occur. The average cost is Cr100 to land and remain for up to six days; thereafter, a Cr100 per day fee is imposed for each additional day spent in port. In some locations this fee will be higher, while at others local government subsidies will lower or eliminate it.
With the berthing cost I may even use the T20 table of starport fees pg 350 T20 The Travellers handbook.
