How to find the best Intersky fares
Booking out of FDH is usually the strongest fare play: Intersky concentrates 6 of its routess from Friedrichshafen, and higher route density at a hub means more head-to-head competition — both from other Intersky departures and from rival carriers serving overlapping city pairs. Use the Kayak search box above with origin set to FDH to see the airline's full departure board at a glance.
All route, hub, destination and country figures are computed directly from the OpenFlights public-domain routes dataset(openflights.org/data.php)— specifically the directCarriers JSON field on every FlightRoute row, where each airline code (e.g. 3L) is parsed from the OpenFlightsroutes.dat airline identifier column. Carrier names come from the companion OpenFlights airlines.dat dataset. No prices or fare estimates appear on this page — those values fluctuate continuously across 100+ booking sites and are fetched live via Kayak at search time.
