Here is how the Flybussen Stavanger - Kolumbus partnership works:
You save money TO the airport:
All one-way bus trips with Kolumbus (either ticket or Kolumbus card) gives you a price discount (kr 41,- or kr 21,-) when you buy your tickets on board Flybussen Stavanger.
You save money FROM the airport:
Everyone who buys a ticket with Flybussen Stavanger gets a free 1.5 hour transfer to Kolumbus' buses when you show your Flybussen ticket.
Conditions:
Discount is limited to Kolumbus ibuses in Stavanger, Sandnes, Sola, Randaberg, Rennesøy and Ålgård. The transfer must occur within 1,5 hours.
Tickets for trips from the airport can be bought onboard or at flybussen.no.
The discount does not apply to round trip tickets.
