The authorities have made it made it mandatory for passengers in domestic flights to carry proper identification cards. For Nepali citizens, the citizenship certificate, driving license, passport or other IDs can be accepted. Students can show their student IDs while the minors can fly based on IDs of their parents. The new rule has been introduced after it was revealed that passengers of ill-fated Tara Air had lied about their nationality. The aircraft had crashed nearly two months ago.
