How many 380s a small operator would need to operate eg MAD-GRU-EZE daily ? One could even do some direct and returns to GRU/EZE like every other day.. I guess 2, but then the AC/ would be underutilized ? How do you make for service when A/C is serviced ? What you've to do is lease 2 x 340 ?
Having some understanding of what kind of company marsans is (see air comet and handling of aerolineas argentinas so far) I think having them really order 380s and pay for it is surprising. They also failed to buy Spanair. I think the most likely they will have to resell the orders.
