If sufficient seats are available on the desired same-day Northwest or Northwest Airlink-operated domestic flight, Northwest will confirm customers traveling on non-refundable tickets for the alternate flight or flights for the $25 FlyNow fee. Customers traveling on refundable tickets will continue to have the ability to confirm same-day flight changes without incurring a fee.
 

Northwest WorldPerks Elite customers will still maintain the ability to stand by for alternate flights throughout the entire day of departure and will not incur a fee if a seat becomes available. Beginning April 24, all other customers traveling on non-refundable tickets will be charged a $25 fee for same day flight changes, whether boarding via standby status or confirming through the FlyNow option. The $25 fee for boarding via standby status replaces the current option that allows non-Elite customers traveling on non-refundable tickets to stand by for eligible flights at no cost.

The FlyNow option is available to customers checking in on the day of departure for flights within the continental United States, Alaska and to or from Canada.
