This is the worst airline ever! Look for another airline unless you want to get stuck at the airport for hrs or risk getting to your final destination a few days late. The fleet of airplane that Meridiana uses are old and the service is extremely poor.
Just back from a week in Florence/Siena. Flight fine. No delays, courteous staff, comfy seat, no trouble or queues at check in (except for security of course). You do have to pay for any snacks on board but you can always take your own peanuts. Would use them again.
