I'm a little concerned about an upcoming trip from EWR to HKG in December. I have to go there on business and have booked two family members to meet me there a week later. I am not worried about my ticket as my company can absorb the cost. However, with the trouble currently plaguing the airlines and the looming uncertainty of world events, is there anything I should do for my family's tickets? Should I take insurance on them? Leave it alone? I fully intend to go on the trip unless travel advisories caution against it or if my business plans change.

Thanks in advance for your help.
