XJT: Complicated. If you are on the COEX side:
1. CAL benefits for parents, wife, and children.
2. CAL flies to Europe and Japan
3. You and your family can get ID90s on other airlines. We have various agreements with many airlines worldwide. HOWEVER, if you are not married and have your girlfriend as your travel companion (like I do), then they ONLY get CAL benefits. I found out the hard way..
