Free, discounted public transportation rides for children
Public transportation in Shanghai has taken a family-friendly approach to travel by providing free or discounted rides for children. In this article, we'll explore the benefits offered to children traveling on Shanghai's buses, metros, and ferries.
Bus

You are allowed to bring two children under the height of 1.3 meters for free. For any additional children, you'll need to buy tickets. Preschool children unaccompanied by an adult are not permitted to board.
Metro

You are permitted to bring more than two children under 1.3 meters in height onto the metro for free. Preschool children are not advised to travel unaccompanied.
Train

Passengers can bring one child under the age of 6 onto the train for free, but the child must not occupy a separate seat.
If you want to reserve a seat for your child, you'll need to buy a child discount ticket. Please note that the child's age is calculated based on the travel date.
If you have more than one child under 6, you must buy them a child discount ticket, which is half the price of a full fare ticket.
You'll need to purchase a child discount ticket for children aged between 6 and 14, and a full-price ticket for a child aged 14 or older.
If you are traveling with a child eligible for a free fare, you must declare this to the railway operator at the time of booking. And you will need to present the valid identification document of the child used during the ticket purchase when boarding the train.
Airplane

Fares for children differ among airlines. Below are some examples of how airlines may price tickets for children.
China Eastern Airlines
You can purchase a child ticket with a seat at half the adult fare for the corresponding cabin class for children aged between 2 and 12.
If you have an infant between 14 days and 2 years old, you'll need to purchase an infant ticket without a seat at 10 percent of the adult fare. If a seat is required for the infant, a child ticket must be purchased.
If you are traveling with more than two infants, you should buy a child ticket for each of the additional infants and a seat will be provided.
