Beijing Capital International Airport announced that it remained world's second-busiest airport last year in terms of passenger throughput.
Passenger volumes grew 4.2 percent year-on-year to reach 81.8 million last year, according to a statement from the airport. The number of daily passengers exceeded 278,000 during peak travel periods in 2012, the statement said.
Beijing Capital International Airport is located northeast of Beijing. Over 70 domestic and foreign airline companies are participating in the operational business, including over 10 domestic companies and about 60 foreign companies.
The airport has become increasingly busy in the last decade due to China's robust economic growth. Ninety-four airlines were using it as a flight hub as of the end of last year, operating flights to 236 destinations, according to the statement.
