SAS experienced technical problems during Tuesday afternoon. Passengers have not been able to check in or download boarding passes.
It has also not been possible to buy tickets with Eurobonus or add extra baggage.
The problem is said to have started at 4 pm and about an hour later the problem is reported to be resolved.
It was an internal internet problem. Now it is possible to check in and retrieve boarding cards again, and that is the most important thing, says SAS press spokesperson Lars Andersen.
Corrected: In an earlier version, the wrong day was stated for the technical problems.
