There has been ongoing media discussion about this for months, however many believe it unlikely that a healthy, listed airline has any interest in an ailing mess such as Alitalia. Many reports are probably fanciful thinking of those in Italy who have yet to come to terms with the flag carrier's demise.
However, stranger things have happened - if it is taken over, it is unlikely to survive in its current form.
If I were in an Alitalia union, I would continue to milk it, as the useless Italian governments have shown themselves to be prepared to support it at almost any cost!
