Hi! I have $1400 in FFC that expires February 7. I've found a booking on Lufthansa that allows me to fly Rome-Bangalore/ Bangalore-SFO/JFK-Rome for about $1700, but only the first flight would be before February. Can I book all three using the FFC?

Also, UA won't even show me the flights on its website. So would this require a phone call or some other internet strategy?

Thanks for your help.
