Unfortunately, there is no way for me to know what happened or why you are being asked to go to Boston Logan. There could be several reasons, not the least of which is that there are literally millions of people who are now seeking to join the Global Entry program.
When did your husband join the program?
OK, no problem, I understand. Since Global Entry is not administered by the TSA, you should not contact them. They will not be of any assistance.
Global Entry is a Trusted Traveler program, which is administered by Customs and Border Protection (CBP). If you have issues with a Trusted Traveler Program, you should contact the CBP at 855 - 873 - 4637.
Best of luck.
