Yes this is a great benefit and one to verify. These credit card threads can really be helpful for some. I learned the hard way that it is important to let your credit card company know about travel, especially international travel. My VISA card was cancelled on one trip to SXM, and that was the only card I had with me at the time. The only thing that saved me was a friend we traveled with who paid for everything until we got back home.
I now have multiple credit cards (ones with no fee for international transactions) and definitely notify them when I travel.
