Many people remain divided over the use of Beijing's Airport Express link.
"The line is reliable in terms of traveling time, but I prefer cabs when I have luggage."
Zhang Yiqun, journalist in Beijing
"I seldom use the link because it takes me about one hour to get to the Airport Express station and another half hour to finally arrive at the airport; it takes me only half an hour by taxi if the traffic is not bad."
Liu Jiangbo, State-owned company employee in Beijing
"The Airport Express saves me money. But if the flight is late at night, it's better to take a taxi because the line may not be open at that time."
Rebeca Ruiz Contreras, from Mexico, a master's student of Chinese language and culture at Beijing Language and Culture University
"Considering the traffic jams during rush hour in Beijing, I prefer to take the Airport Express, which is punctual and allows me to manage my time better."
Cenk Ozkomur, news editor from Turkey in Beijing
