Still not convinced you are for real....but if you are...
The Tristar is a nice aircraft and nostalgia has it's place....but.
Why start an airline with an aircraft where flight deck crew costs, fuel costs and maintenance costs are fifty per cent greater than the 767 or A 300/310.
Those fifty per cents add up to a very very large amount of money. Witness the fact that all the major airlines and most of the minor airlines consider it past it's sell by date and uneconomical to operate.
I also think it's maybe a bit big for testing the market on a relatively small catchment area.
With the best will in the world, I don't think I would invest under those conditions or leave a secure job to fly them.
I do wish you success (if you are real) and I hope it works. Me? I'd fork out for the increased leasing costs of a twin jet and make a profit. (or a smaller loss)
