SLOULIN FIELD INTERNATIONAL AIRPORT Latitude and Longitude:
Sloulin Field International Airport ( IATA: ISN, ICAO: KISN, FAA LID: ISN) is an airport serving Williston, a city in North Dakota. It is two miles north of downtown and is owned and operated by the City.   Built in 1947, the airport faces expansion constraints, design issues, and the need for runway refurbishment. For these reasons, as well as the rise in air traffic amid the North Dakota oil boom, officials have decided to build Williston Basin International Airport. This airport will replace Sloulin Field Airport, which will be decommissioned. ISN covers 740 acres (299 ha) of land. 
The first airport to serve Williston, North Dakota, was east of the city near Little Muddy Creek. The environment was unsuitable, and operations shifted to a new airport in 1936. The 23-acre (9.3 ha) site became too small, so Sloulin Field International Airport was built in 1947. 
Sloulin Field Airport faced various problems as the city grew. The 2004 master plan noted limited room for expansion because of the surrounding terrain and buildings, design issues that conflicted with the Federal Aviation Administration's standards, and the need to refurbish the runway. Runway improvements had also been recommended in the 1993 master plan. 
A $4 million renovation project included the construction of a new terminal that opened in October 2006.  When Delta Air Lines and United Airlines announced plans to serve Williston in 2012, airport officials decided to add a mobile home trailer to provide additional capacity for the terminal. 
In light of the issues highlighted in the 2004 master plan and increased air service to Williston amid the North Dakota oil boom,  plans either to renovate Sloulin Field Airport or to construct a new airport surfaced in 2011.  Officials ultimately decided to build Williston Basin International Airport because of cost considerations. Sloulin Field Airport will be decommissioned, and the land will be sold. 
Sloulin Field Airport has a 9,600-square-foot (890 m2) terminal with a 1,500-square-foot (140 m2) mobile home trailer that provides extra seating capacity.   The terminal has one gate and vending machines for passengers.  
As of October 2016 Delta Air Lines and United Airlines fly to Minneapolis and Denver, respectively. The airlines together offer five flights per day to Sloulin Field. The airport saw eleven flights per day, including nonstop service to Houston, at the height of the oil boom.

The airport is so stretched with only one gate that it uses a trailer to cope with extra passengers in the holding area.
