Flytoget's machines and desk are what you meet first, and the airport sells the express as the fastest way in. The Vy trains on lines R12, RE10 and RE11 use the same station under the terminal and cost 134 kr on a four-zone Ruter ticket - 142 kr less per person for a journey four minutes longer. Flytoget's own conditions say its ticket is not valid on other lines, and a Ruter ticket is not valid on the Flytoget.
The temporary maximum prices for street-hailed taxis were not renewed, so a hailed car at the airport charges its own tariff. Reported cases at Gardermoen include 3,700 kr for a 4.4 km ride and a 21,230 kr charge into the city. Avinor's own taxi page warns against getting into a taxi without pre-booking, or making a deal with a driver inside or outside the terminal.
The same adult seat is 279 kr on flybussen.no, 289 kr at the ticket machine and 319 kr from the driver, per the operator's price table valid from 1 April 2026. On Vy, buying on board adds a 40 kr surcharge at any station that has a ticket machine - and Oslo Lufthavn has machines.
Oslo Lufthavn is in Ruter zone 4N, not zone 1. A one-zone ticket (46 kr) or a day pass bought for the city stops short: the airport needs a four-zone ticket at 134 kr, or an add-on for the missing zones if you already hold a period ticket.
