The following search modes are available:

• standard search which lets you simply pick a country to start from, and then narrow down your selection by picking the destination region, country and airport.
• advanced search which enables you to quickly find a route if you know the airport ICAO codes.
• booking mode, where a list of your upcoming flights is displayed and you can quickly begin briefing for a scheduled flight.

There is also a tab "Add new route" which as the name indicates is used for adding your own routes to vroute.info database.
