We recently were booked on a low fare flight within Italy by our travel agent. We were advised that luggage was not included but could be added at checkin for euro13. This information was written on the printed itinerary provided to us by the travel agent. While not happy about this we accepted it. However we were unable to check in online despite being repeatedly advised that we could do so, and at the airport were charged euro40. (Au$60)/ bag. We were sent to an Alitalia agent at the airport because Alitalia could not check us in until we had a paper ticket. All very strange. YOU HAVE BEEN WARNED.
