It sounds like the OP has booked everyone's ticket with his/her own United Card. If so, OP should read the T&C carefully as it might cover family members but not necessarily a more general group unless each ticket was paid with the United Card.
Unless OP has special knowledge, perhaps he/she shouldn't advise the kidney donor regarding travel medical insurance. He should insist that the person be covered, but finding or suggesting policies would seem to require specialized knowledge.
In fact, is it generally medically advisable for a recent kidney donor to undertake inessential travel to a third world country? Will the group go to isolated or rural areas where good competent medical care might not be available or where an emergency medical evacuation is likely to be delayed?
