Back of the napkin, 100,000 seats sold at a generous average of say $75 per seat would have generated $7.5 million in revenue. Their aircraft leasing costs alone for their four jet fleet would run to around $1.5 million a month. Given the staggered fleet delivery their leasing costs to date would be in the order of $5.4 million.
Mature state, with an all leased fleet, you'd expect leasing costs to be between 10 - 20 percent of total operating costs, maybe a smidge higher depending on how tightly they've ratcheted down their other expense lines.
