Des Moines International Airport (IATA: DSM, ICAO: KDSM, FAA LID: DSM) is a public small hub primary located three miles (5 km) southwest of the central
business district of Des Moines, a city in Polk County, Iowa, United States. This airport is publicly owned by the City of Des Moines. The airport serves
the Des Moines metropolitan area and is the closest airport with 18 connections to major airline hubs for people who live throughout much of east-central,
north-central, and southern Iowa.
Eppley Airfield in Omaha and the Kansas City International Airport compete with Des Moines International for business. Recently, fewer locals than in
past years choose to fly out of those airfields even though both airports offer discount airlines not available in the Des Moines market. Local usage
has improved thanks to Des Moines International Airport airing television commercials pointing out that passengers who choose to fly out of Omaha or
Kansas City prevent Des Moines from attracting new airlines. Des Moines also has discount service from Allegiant Air, not available at Omaha. This
has led to record-breaking years, and the airport handled a record 1,990,167 passengers in 2004; that figure dropped to 1,903,573 in 2005 but increased
to 1,959,393 in 2006.
Booming enplanement rates and the aging terminal have led Des Moines International's board to begin planning for further expansion. The present terminal
would be replaced to allow for expanded cargo operations and a planned general aviation runway would be expanded to a full service runway. These plans
are expected to be put into place once the airport handles approximately 3 million passengers a year, or 1.5 million enplanements.
