SAS has cancelled 1,200 flights in May because of fuel shortages, disrupting travel plans across its network and leaving passengers facing last-minute changes.

The airline said the cancellations were linked to problems securing fuel, but it has not given a full breakdown of the routes affected. The issue is expected to hit both domestic and international travellers, with knock-on effects for connections and onward journeys.

Passengers booked to fly with SAS in May have been advised to check their flight status before travelling and to monitor updates from the airline. The carrier is working to manage the disruption while arranging alternatives where possible.

Fuel supply problems can create wider pressure on airline operations because aircraft turnarounds depend on tight schedules and available stock at airports. When shortages emerge, carriers often have to cancel flights, consolidate services or rebook customers on later departures.

For travellers, the immediate impact is likely to be longer waits, reduced choice and possible extra costs if alternative flights are limited. Those with tight onward connections may be among the most affected, especially on routes where SAS is a major operator.

Airlines normally try to protect the busiest services first, but a shortage can force broader changes across a monthly schedule. The scale of 1,200 cancellations suggests the disruption is likely to be significant for SAS passengers throughout May.
