49 USD to NYC from DR is not possible, but 49 USD plus fuel tax and all local taxes will be miren than Delta.
DR has no alternative airports for low cost carriers, Operational cost in DR will be much higher than in Panama, so I do not know Howe they plan Tom eclipse Copa.
The point you raise about alternative airports is a valid one.
Many lcc’s and Ulcc’s usually seek out secondary airports as they tend to cost less to operate out of.
LA Isabella would be a natural option for flycana, but for the fact the runway is a bit short of what is likely needed for the proposed A320’s they intend to use.
Assuming they use the max passenger configuration planes, they will need to fill approximately 80% of the 180 plus seats to maintain profitability at either lcc or ulcc price points.
Is there that much demand initially out of/into Santo Domingo to justify the costs of operation. Perhaps a regular shuttle run into the US......but flights to the US will not come for some time........and they definitely will not be $49.00 with or without taxes. The A320’s seem to be a bit ambitious in their plan, but they do have management with experience.
A better fit might be the smaller Brazilian Jungle jets......but I think they are fuel hogs.
Kudos to them for trying though.
