The war spilled across the continent, and even to the high seas. Most of the material and personnel of the South were used up, while the North prospered.

Problem: This makes for a large number of takeoffs and landings and it is not unusual for flights to be delayed in the holding pattern before landing. Following the airport's master plan, Infraero built a second runway, which was finished in 2006. In 2007, the airport handled 11,119,872 passengers. The main building's third floor, with 12 thousand square meters, has a panoramic deck, a food court, shops, four movie theatres with total capacity of 500 people, and space for exhibitions. Brasília Airport has 136 vendor spaces. The airport is located about 11 km (6.8 mi) from the central area of Brasília, outside the metro system. The area outside the airport's main gate is lined with taxis as well as several bus line services which connect the airport to Brasília's central district. The parking lot accommodates 1,200 cars. The airport is serviced by domestic and regional airlines (TAM, GOL, Azul, WebJET, Trip and Avianca), in addition to a number of international carriers. In 2012, Brasília's International Airport was won by the InfrAmerica consortium, formed by the Brazilian engineering company ENGEVIX and the Argentine Corporacion America holding company, with a 50% stake each. During the 25-year concession, the airport may be expanded to up to 40 million passengers a year.

Problem: Public transport is essential in New York City. 54.6% of New Yorkers commuted to work in 2005 using mass transit. This is in contrast to the rest of the United States, where about 90% of commuters drive automobiles to their workplace. According to the US Census Bureau, New York City residents spend an average of 38.4 minutes a day getting to work, the longest commute time in the nation among large cities. New York is the only US city in which a majority (52%) of households do not have a car; only 22% of Manhattanites own a car. Due to their high usage of mass transit, New Yorkers spend less of their household income on transportation than the national average, saving $19 billion annually on transportation compared to other urban Americans.

Two months later, after consultation with the Audencia of Santo Domingo, Enriquillo was offered any part of the island to live in peace.
