Norway’s air traffic controllers walked off the job Friday morning after wage and working-conditions talks with their employer collapsed, cancelling at least 31 Norwegian Air Shuttle flights and eight SAS flights by the end of Friday — with the hardest disruption still ahead: Oslo Airport Gardermoen will be completely closed to all commercial traffic for five hours Sunday morning, and western Norway’s airspace faces severe restrictions Saturday evening. The strike is expected to last through Monday, August 24, and both Norwegian and SAS have opened free rebooking waivers that passengers must act on before their departure date to avoid losing their place in line.
The Norwegian Air Traffic Controllers Association, known in Norwegian as Norsk Flygelederforening (NFF), called out 12 controllers beginning at 6:30 a.m. local time on Friday, August 21, targeting Oslo Airport Gardermoen (OSL), Bergen Airport Flesland (BGO), and the Røyken control centre, which manages approach and regional traffic for all of western Norway. Because the walkout encompasses the Røyken centre, the impact is national — not limited to the two airports initially named. State mediator Mats Wilhelm Ruland, who spent seven hours in overtime talks before declaring the negotiations failed at midnight Thursday, told reporters there is currently no basis for resuming mediation and that the responsibility for resolving the dispute rests with the parties themselves.
According to FlightAware data cited by Travel Market Report, Oslo Gardermoen logged 154 flight delays and 11 cancellations on Friday; Bergen Flesland recorded 21 delays and two cancellations. Because the walkout officially began at 11:00 a.m. local — midmorning — those numbers capture only a partial day of disruption, and Friday evening delays cascaded across the entire national network, according to airport operator Avinor.
Why Oslo Airport Will Be Closed for Five Hours Sunday Morning
Avinor Flysikring has published a four-day impact assessment covering the full arc of the disruption. Saturday, August 22 brings moderate delays at Oslo and increasing disruption at Bergen through the day, with significant western Norway airspace restrictions and periodic closures expected by evening. Sunday, August 23 is the peak: Gardermoen closes entirely to commercial traffic from 6:30 to 11:30 a.m. local time — a five-hour window covering the early-morning wave of departures — with major delays and cancellations rippling nationwide throughout the rest of the day. Monday, August 24 carries aftereffects: fewer disruptions at OSL and BGO during the morning, but western Norway faces renewed delays into the afternoon and evening as aircraft and crew work back into position.
The closure window aligns with the shift start time for the striking controllers. Even the absence of a small number of controllers in this centralized system creates cascading effects — the NFF’s 12 members cover positions critical enough that their combined absence means safe operations at normal capacity cannot be maintained during those hours.
The Dispute Is About Working Conditions, Not Just Pay
The gap between the two sides is wider than a pay figure suggests, and that matters for the likelihood of a quick settlement. NFF leader Robert Gjønnes has said publicly that the dispute centers on working conditions — specifically required break times, life-stage policies, and rules governing instructor duties — rather than solely on compensation.
Spekter, the employers’ association representing airport operator Avinor in the negotiations, has pushed back sharply. CEO Anne-Kari Bratten called the walkout “incomprehensible,” noting the union had rejected an offer of an average annual salary increase of 62,000 Norwegian kroner — a raise Spekter characterized as roughly 4.4 percent, which would bring the average controller salary to approximately 1.7 million kroner. “This is one of the highest-paid groups in Norwegian employment,” Bratten told public broadcaster NRK.
The public mediator’s declaration that there is no current basis for resumption, combined with Gjønnes’ framing of the dispute as structural rather than financial, signals that passengers should not assume the strike resolves before Monday — and should plan for the possibility it extends.
What Do Waivers from Norwegian and SAS Actually Cover?
Both major Norwegian carriers have issued travel waivers, but the terms differ and carry important limits. SAS is offering free voluntary rebooking for passengers traveling to or from Oslo Gardermoen (OSL), Bergen Flesland (BGO), Stavanger Sola (SVG), Kristiansand Kjevik (KRS), Ålesund Vigra (AES), and TrondheimVærnes (TRD) on August 21 through 24. Rebooking must be onto SAS-operated flights between August 20 and August 28 in the same service class; the waiver does not cover rebooking onto other airlines. Travelers who bought tickets through a travel agent or tour operator must contact them directly rather than using the SAS website or app.
Norwegian Air Shuttle has similarly confirmed it will contact affected passengers by SMS and email and will assist with rebooking, accommodation, and meals, or issue a refund for passengers who choose not to travel. The airline has said it intends to prioritize protecting its infrequent — specifically weekly — services to avoid leaving passengers and crew stranded abroad.
One catch that catches many passengers off guard: Avinor and passenger rights experts both advise travelers not to cancel their own booking before the airline formally cancels the flight. Self-cancellation forfeits rebooking and refund rights. Wait for the airline to contact you, or check the airline’s flight status page directly.
Will You Get Cash Compensation Under EU261?
Probably not — and the reason is a legal classification that trips up most travelers in this situation. Under EU Regulation 261/2004, airlines are required to pay fixed compensation of €250 to €600 when a flight is cancelled or delayed more than three hours at arrival — but only when the airline is legally responsible for the disruption. Third-party strikes, specifically including air traffic control walkouts, are classified as “extraordinary circumstances” that exempt the airline from cash compensation. The European Court of Justice confirmed in a 2021 ruling in AirHelp v. SAS that a strike by the airline’s own staff does not qualify as extraordinary circumstances — making the airline liable for cash — but that the reverse applies to outside parties like ATC.
What EU261 does guarantee, regardless of who caused the disruption: duty of care — meals and refreshments proportionate to the wait, and a hotel plus transfers if you are delayed overnight — plus a choice between a full refund of the unused ticket and rebooking to your destination on the earliest available flight. Nora Wennberg Gløersen, a consumer lawyer at the Norwegian Consumer Council, has noted that airlines carry an “obligation to get you to your destination as soon as possible,” which extends to rebooking passengers onto a competing carrier if the airline’s own schedule cannot accommodate them in a reasonable timeframe. Keep receipts for any meals or accommodation you pay for out of pocket; you can seek reimbursement from the airline.
One additional catch: travel insurance. Norwegian insurer Fremtind has confirmed in a press release that standard travel insurance policies in Norway do not cover costs arising from strike-related delays or cancellations. Passengers holding international policies should verify their own terms.
Saturday and Monday: What Travelers Should Expect at Each Stage
For travelers in the air or at airports right now, Saturday, August 22 brings a morning that is manageable at Oslo and a deteriorating afternoon and evening at Bergen and across western Norway. The situation is fluid: Avinor is assessing each flight individually and advises passengers who have not received a cancellation notice to proceed to the airport as scheduled and monitor their airline app for updates.
Sunday, August 23 is the session to avoid if travel can be rescheduled. The complete Gardermoen closure from 6:30 to 11:30 a.m. local time means any Sunday morning departure from OSL is at very high risk of cancellation or severe delay; the effects will carry through the day nationally as repositioning aircraft and crews adjust. Travelers booked on Sunday or Monday flights should check their airline’s flight status page — Norwegian at norwegian.com/en/flight-status and SAS at flysas.com/en/flightstatus — before heading to the airport.
Widerøe, which recorded 14 delays and seven cancellations on Friday alone, is also substantially affected on domestic routes and has not yet published waiver terms as of this writing. Passengers on Widerøe flights should contact the carrier directly.
