The Flights/Trains search option enables you to search for both flights and trains that cover the same route. In this way you can easily compare prices, journey times and other features between the two.
Alternatively you can choose the Flights option or the Trains option to restrict the results to that mode of transport.
For both air and rail searches, you can choose whether to specify a preference for departure time, arrival time or both. The search results are affected by this, and by other rules configured at your administration site. For more information, see the Administration Guide, available from your Support representative.
