Air travelers holding electronic tickets will be able to check-in their own luggage from next year at self-service machines at Shanghai's Pudong International Airport, authorities said on Nov. 19.

The six machines are used by more than 1,000 travelers every day, with most using them to print out boarding passes for international flights.

They will be upgraded so passengers can check-in their luggage at the same time from March next year, said the airport authority.
