Ahh, I didn't know that! It has been ticketed already. I was only told that I could change the routing without a payment of $100 for the booking, and that date changed were free, subject to availibility. I didn't even think to ask if I could change carriers!~

If the worst of my worries is having to take a BA first instead of a JL first flight or vice versa, I am pretty lucky!

Now all I need to do is work out the program between VIE and FCO!
