I have a sleeper booked through AGR, traveling from A to B.
I have a friend who lives several stops from B and might join me for a couple of days in B.
Since the sleeper is booked with points, can I add him to an open sleeper ticket using points, or will he have to pay cash?
If he does pay cash, is the open sleeper + points + cash formula going to make the reservations system explode?
How do I do this? Am I going to make a CSR's day complete and utter hell?
