According to the department, international organizations, tourism businesses and foreign investors usually complain they face difficulties and have to spend much time waiting at the airport, especially in immigration procedures areas.

To improve the performance of the airport’s immigration counters, the department has asked for a separate line for business class passengers and foreign investors.

It also proposed a priority service at the counters for passengers who are willing to pay an extra fee.

Last August, automatic immigration gates opened at the airport, helping save time for tourists. However, the city’s tourism authority still receives much feedback from tourists about having to queue for hours to complete the immigration procedures.
