WUHAN -- China Eastern Airlines will officially offer WiFi on a flight between Wuhan, Central China, and Sydney, on Monday, company sources said Sunday.

This is the first flight from Wuhan to offer its passengers Internet access, said Mei Xiaoling with the airline's Wuhan subsidiary, adding that mobile phones must still be switched off during the flight.

Passengers should reserve in advance, as the service is limited to 100 passengers on each flight, according to the company.

The airline company launched its Wuhan-Sydney route in January. An Airbus 330 departs Wuhan at 11:40 pm on Mondays, Wednesdays and Fridays (Beijing time), and leaves Sydney on Tuesdays, Thursdays and Saturdays at 10:15 pm (local time).
