The Delta A320 landed at Ellsworth Air Force Base at 8:42 PM (Central Time) on Thursday, when its destination was an airport in Rapid City, board spokesman Peter Knudson said yesterday.
Ellsworth is about 10 miles due north of Rapid City Regional Airport. The two airports have runways that are oriented nearly identically to the compass, from northwest to southeast.
Delta Flight 2845 had departed from Minneapolis.
Delta has contacted the passengers "and offered a gesture of apology for the inconvenience," the airline said in a statement.

The Air Force said in a statement that said base officials "followed the proper procedures to address the situation" and ensured the safety of those at the base and passengers. The base did not immediately respond to a request for information about the specific procedures and whether air traffic controllers at the base where in contact with the pilot and authorised the landing.
Landings at wrong airports by commercial pilots, while unusual, are still more common than many passengers may realise or airlines would like to acknowledge.
Of the 35 documented wrong landings, at least 23 occurred at airports with shorter runways, creating potential safety issues.
On January 12, 2014, the pilots of a Southwest Airlines Boeing 737-700 stopped their plane just short of a ravine at the end of a short runway in Hollister, Missouri, when they had meant to land on a runway twice as long at nearby Bronson.
