In R0 there is a flaw in the DAL political restriction.
Once you establish a route conforming to the DAL restrictions limiting long flights to aircraft that can carry 56 passengers or fewer, one can swap out the aircraft for a larger one that does not meet the restrictions. For example, I had established a route between DAL and SEA with a Martin 4-0-4 40 seats, and later changed it for a DC-10-40 399 seats.
Airport NQN Nequen - Presidente Peron, is showing as being located about 300mi off Long Island New York. It looks like the latitude is listed as north rather than south.
