cost of 737-300?

[markbusby]

Could you please supply me with rough figures for the following details:

cost of new boeing 737-300

annual cost of maintenance (if possible, amount of flight hours that determine this)

average life span of boeing 737-300

I am investigating the cost per kg of running the plane and so need these to help with calculating fixed costs.

landing/parking tax (for one trip only, flying to kiev)

Thanks again,

Mark.
