From here, trains depart for St Pancras International station in 25 minutes, with frequent services operated by Thameslink.

The London City airport occupies a unique location just 11 kilometres east of London’s city centre, in the heart of the Docklands financial district. Its privileged location makes it particularly popular with business travellers, with flights mainly to key European destinations.
The main advantage of this airport is its accessibility via the DLR (Docklands Light Railway), which connects the airport to Bank station in just 22 minutes. Trains are frequent and the service is integrated with London’s underground network, making it easy to reach any part of the city.
