"We have received an airplane from the United States. We gave it clearance to land, which it had asked for," Carl Selling, spokesman for the Swedish Aviation Authority (Luftfartsverket - LFV) told AFP.
"It was a business jet. It landed at around 8.30am," he said, adding that "we have opened (a narrow corridor of) airspace to Norway and the Norwegian Sea."
On Sunday, as the vast cloud of Icelandic volcano ash that has paralysed air travel in Europe shifted, Norway opened a wide stretch of airspace from the central town of Kristiansund up to the northern region of Finnmark.
Norway and Sweden both temporarily reopened some airspace on Friday, and pockets in northern Norway remained open on Saturday.
