Malev, the Hungarian state airline,
has collapsed. Ryan Air has announced that they'll start a new small base in Budapest in two weeks, including Thessaloniki. But Athens-Budapest was a monopoly route for Malev, and
there's speculation that Aegean could be starting up that route (although Olympic is another possibility).
The collapse of Malev comes soon after Spanair folded. Aegean stands to benefit if it is one of the survivors. As far as I know, Aegean is not receiving state aid and thus is not vulnerable to the same financial problems that Spanair and Malev had.
