London City Airport has launched a new Facebook Messenger functionality, enabling passengers to get information about their upcoming flight on their mobile device.
Users, with the application installed, can message the LCY Flight Info Facebook page with their flight number to receive real-time flight information. This includes departure and arrival times, and also the relevant boarding gate information. Both departing passengers and those waiting to collect arriving passengers at the airport will be able to use it.
