How to find the best Great Lakes Airlines fares

Booking out of DEN is usually the strongest fare play: Great Lakes Airlines concentrates 14 of its routess from Denver, and higher route density at a hub means more head-to-head competition — both from other Great Lakes Airlines departures and from rival carriers serving overlapping city pairs. Use the Kayak search box above with origin set to DEN to see the airline's full departure board at a glance.

Data sources & methodology

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. ZK) 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.
