Bit of a complicated case this everyone!
Planning to book 4 reward seats LHR-DEL-LHR using 1 AMEX 241 and rest points.
We will all fly out together. My question is can I change only my (card holder) inbound leg whilst still allowing the rest (3) of my family to fly at the later original inbound date?
Or does this go against the Q: Can I book myself on one flight and my companion on the next flight?
A: No. You must fly on the same flights, in the same cabin. This also applies to all four passengers if the booking has been made by a Premium Plus Cardmember using two vouchers in the same booking.

Issue is that I need to come back home early whereas the rest of family wants to stay for a few more weeks.
