VietJet Air said Tuesday that one of its domestic Vietnamese flights landed at the wrong airport last week and it is waiting for the results of an official inquiry into the incident.

VietJet Air Flight VJ8861 landed at Cam Ranh airport near Nha Trang City in central Vietnam on June 19 instead of Liên Khương airport near Đà Lạt City in the country's Central Highlands, as scheduled, the budget carrier said. The two cities are more than 100 kilometers (62 miles) apart.

The airline, which operates 15 Airbus A320 single aisle jets, didn't explain how the plane landed at the wrong airport, saying it is waiting for details from an investigation. The plane carried 180 passengers, according to information provided by the airline's external public relations firm.

"We are working in close partnership with the Civil Aviation Authority of Vietnam to thoroughly investigate the incident and ensure that this does not happen again," the carrier said.

The Civil Aviation Authority of Vietnam said over the weekend it has suspended all members of Flight VJ8861's crew pending results of the investigation. The regulator said its preliminary findings show flight coordinators, the crew, including the pilots, and the ground staff involved with the flight didn't follow proper procedures.

"This is a serious incident…posing [a] threat to aviation safety," the regulator said.

Though rare, there have been other incidents of aircraft landing on wrong runways or at wrong airports. In November last year, a Boeing 747 Dreamlifter jet, used to haul large plane parts for manufacturing, mistakenly landed at a small Kansas airport amid apparent confusion by its pilots. It touched down at Colonel James Jabara Airport in Wichita, Kan. instead of McConnell Air Force Base about 10 miles to the southwest.

Owned by Vietnam's Sovico Holdings, VietJet Air started flight operations in 2011. The airline flies to more than 10 destinations in Vietnam and to Bangkok and Singapore.

VietJet Air hasn't had any serious incidents previously, but the airline was reprimanded and fined by the Civil Aviation Authority in 2012 for staging an in-flight Hawaiian-themed dance performance by beauty-contest participants without first getting permission from the regulator. VietJet Air said its No. 1 priority is passenger safety.

VietJet Air signed firm orders for 63 Airbus A320 jets, as well as purchase rights for 30 more, in a deal valued at $9.1 billion at list prices at the Singapore Airshow in February.
