Will the next ticket always be cheaper?
Not necessarily. My price depends on your travel pattern over the past 14 days. If you travel less in a 14-day period, the price may adjust.
Example:
From April 1-14, you traveled 10 times, resulting in a price of NOK 37.84 for your next ticket. Then you take a week off and plan to travel again on April 21. The number of trips in the last 14 days has decreased. You traveled five times from April 7-21, so the ticket price will be NOK 41.28. The price will decrease again if you travel more frequently.
