I tried the Orbitz route twice - they're worthless. The TAs see the original fare rules in their system, and will steadfastly refuse to make any desirableamendments to the booking because a) "things are still up in the air", b) "we have to reprice, especially because the ticket is so cheap", or my favorite c) "it doesn't matter what the fare rules and consumer laws say - whatever Alitalia tells us over the phone is what we have to go by".
