I wouldn't worry about it too much if they are scheduled to fly on BA #8110, the 7:00 a.m. AMS-LGW flight, connecting to CO #35, the 9:35 a.m. departure from LGW. Why? Because there are two later CO-operated flights to IAH, the 12:00 p.m. nonstop on CO#5, and the 12:30 p.m. one stop via EWR on CO #29/CO #51.

If a significant delay is posted for the BA flight prior to departure from AMS, CO may be willing to accommodate your family members on the 3:40 p.m. nonstop from AMS-IAH on CO #47.

On what flights are they scheduled to fly?
