Norwegian has changed the way members of its Norwegian Reward frequent flyer programme can claim their points.
Previously, members have to claim their CashPoints at the time of booking. They can now collect them up to 30 days after departure.
CashPoints can be used as full or partial payment for flights, seat reservations or check-in luggage.
Norwegian Reward vice president Brede Huser said: "We are seeing increasing numbers of Norwegian Reward members gain the benefits of flying with us by taking advantage of their CashPoints.
"We now have over three million members... As such, the enhanced Norwegian Reward programme will help reduce costs and deliver great value for Reward members."
Norwegian Reward members who fly 12 round trips between July 1 and December 31 can claim one free long-haul flight.
Earlier this month, Norwegian announced a new transatlantic route, from London Gatwick to Boston (see news, July 9).
