Each eight (8) hour period the plane is parked at EWR, they are charged the 70.00$ fee for public aircraft parking weighing between 100'000 to 200'000 pounds of max take-off weight. Considering the Boeing 757-200 is 255'000 pounds for max take-off weight, they are charged the 25.00$ per 25'000 pounds over the limit and the fraction cost of that. So around 122$ per 8 hours. Meaning if atleast one plane is sitting there for en entire 24 hour period they are paying 488$ every day.
That's ~14'640$ per month for parking one aircraft. Not bad, but consider the airline industry is a place of razor thin profit margins, if they're breaking even on just one route for fuel, airport fees, catering, etc, they must be losing money on that plane too. Not to mention other costs associated such as maintenance, management, IT structure, employees, etc, then they're looking quite thin in terms of being able to expand.
Let's add their new planes to the fleet! Cost of all those involved with lower yields and the economic downturn, you'll be damned if they survive through the next summer! I can go into more specific costs, but overall you get my point. Razor thin margins for a start-up airline and false front claims to assure people. Plus how is it they aren't in some sort of IPO? Baltia has one and they haven't even flown a commercial flight. I'd expect the IPO to raise capital for their expansion.
