According to an airline spokesman, the national flag carrier has recently raised the baggage allowance to 60 kg.
Currently, PIA flies one flight per week on Sundays between Islamabad and Beijing.
The discount may be useful to students who intend to spend their summer vacations in Pakistan or who wish to return home after earning their degrees.
Before, students who wanted to visit China could now receive a 27% reduction on their fares through PIA.
On Eid ul Fitr, the national flag airline also reduced the cost of domestic flights by 20% for both economy and executive economy classes.
