My family and I flew from Rome to Sicily on Blu Express or Blu Panaromic Express and want to report a positive experience. It was a Boeing 737 plane and left on time. The announcements were in English and Italian, but we were the only non-Italians on the plane. Our carry-ons were too heavy for the 5 Kilo limit and were checked. But the baggage arrived pretty quickly at the baggage area.
My in-laws had several horror stories about lost luggage and cancelled flights with Alitalia. Also, Alitalia wanted $600 per person, which was much as our Phila-Rome flight. Blu Express was about $160 per person.
Key: you have to book online in Euros, but they take major credit cards. You don't get a card, but a confirmation number and you take it to the desk. There are only two tiny counters at the Rome airport, way past the Alitalia large counters. You have to look around, but the staff was efficient.
Good airline for our trip and would recommend.
