Hi folks!
The second one was quite well thought thru. Just let me put the structure in here which is used by several economy books dealing with this:
DIRECT operating cost
All that directly comes from moving your A/C from A to B, most of this can be calculated fairly easy per f.h.
1. Crew (flight deck and cabin crew along with ALL their payments! Not to forget secondary salary and allowances etc.)
2. Fuel
3. APT charges
4. En route (ATC)
5. Maintenance (depending on flight hours AND the duty cycles, so you also will need your average leg times...)
6. Depreciatoin (in the current market not to underestimate)
7. A/C rentals
8. Insurance
Then we come to the even more interesting
INDIRECT operating costs:
1. STATION costs (very difficult to get a real numbers here...)
2. Handling
3. Passenger services
4. Sales/reservation
5. Commissions
6. Ads and
PR 7. General/Overhead cost/Admin
8. Other stuff which wasn't mentioned yet
Depending on the A/C type, the routes you fly, the APTs you will use, the outcome can be quite different. In the current European market you should try to achieve a mean production/operating cost of about 0.1 Euro per seat per km.
And as already mentioned, this is not really much to gain from any more. If you see that with some L/R flights a company makes in the end a total yield after taxes of 3000 Euro it is ridiculous to have so many people working on it
Hope this helps somewhat, sorry for the late and lazy response
