The Northern Airport Authority has fined an employee at Noi Bai Airport's parking lot for overcharging customers.
Nguyen Tuan Anh was ordered to pay VND22.5 million, or around US$1,000, for his violation.
On May 8 inspectors caught him asking for VND7,000 per motorbike instead of the regulated rate of VND3,000.
Further inspection also found that he kept recycling old tickets for multiple passengers to steal money from his company.
In March, Noi Bai Airport was named the world’s most improved airport by Skytrax, a UK-based firm which runs an airline and airport ranking site.
